Stops Catalytic Converter thefts! (inexpensive method)

Cost: $40 or less per RV
Time: About an hour.
Level of difficulty: Low

RVs, being somewhat high up to begin with, are easy targets for catalytic converter thieves. I have 3 RVs. One of the cats was stolen one night when I parked the RV in front of my home. It was covered by insurance (~$4000 to replace), but it put that RV out of commission for about 6 weeks to get the insurance claim taken care of, the parts to come in, and to get it fixed. My RVs usually are parked in storage in a yard that doesn't seem like it would be hard for thieves to visit. In fact, I'm actually surprised they haven't all been stolen. So, I decided to do something to reduce my chances of having another one stolen...

An easy way to protect your catalytic converter...
Simple project any of you can likely do...

Supplies:

This was enough to do 2 and a half of my RVs (I have 3 RVs).
Each RV took about 20' of 3/16" steel cable and 14 of the wire rope clamp clips.

For me doing 3 RVs, here is what I needed:
1 can of VHT Orange Hi-temp engine paint: ($15)
https://www.oreillyauto.com/detail/c/flameproof/vht-flameproof-11-ounce-flat-orange-spray-paint/vht1/sp114?q=vht+orange

32 pack of wire rope clamp clips: ($16) (...actually need 5-6 more to finish the 3rd RV) These were much cheaper than buying at Home Depot.
https://www.amazon.com/dp/B083P78JP6

50' of 3/16" UNCOATED steel wire cable: ($27) (...actually need about 10 more feet to finish the 3rd RV)
https://www.homedepot.com/p/Everbilt-3-16-in-x-50-ft-Galvanized-Uncoated-Steel-Wire-Rope-803172/203958869

Cable cutter: ($23 with typical Harbor Freight 20% off coupon)
https://www.harborfreight.com/28-inch-cable-cutters-6649.html
Or, you might have another way to cut this type of cable. Or, you might be able to borrow a cable cutter from a friend... Note: The one in the picture above was NOT enough to cut or even put a dent in this cable, which I guess is a good thing. The 28" one from Harbor Freight worked great. For my install, I started with a 12' piece of cable and wrapped it from the rear to the front and then secured it in one or two places. Then I took smaller pieces of cable (1-3') and attached it at other various places. An alternative, and possible way around not being able to cut the cable (if you don't have a way) would be to purchase a 25' cable and weave/connect it all as one piece through the various attachment points. If you do this, be sure to put lots of the clamps in the appropriate places so that each connection point needs to be cut by a thief in order to remove the catalytic converter.

Heat wraps: ($5) at Harbor freight for a huge assortment. This is to reduce frayed ends when you cut the cable.


Before:



During:



After:



The visual deterrent is hopefully enough to get the thieves to move on to an easier target. On my RVs the cable is independently attached to 6 or 7 different places (including 2-3 from the top which would be harder for a thief to get to in a short time). EACH would have to be cut in order to get the catalytic converter out.

In the absence of all this, a thief with a cordless sawsall would only need to cut through 2 places with easy access (right before the catalytic converter, and right after) and would likely be done in less than 2 minutes. With this system, they would need to cut all of the additional cable locations where it is attached to the frame. This would, I believe, be a bit challenging with a sawsall as the cable will not necessarily remain still while they attempt to cut it. Also, the attachment points up high will be difficult to reach with a sawsall. If they happen to have cable cutters with them (...I'm guessing most of the time they do not), it still creates a situation where they will have to spend significantly more time trying to remove an orange catalytic converter (...which effectively flags the catalytic converter as stolen to authorities and some who are receiving/recycling these).

The clamps are just held on with 2 nuts. I don't think a thief would ever spend the time unbolting all of them as it would take them probably 20-30 minutes to do so.

So, for ~$30-40 you can probably reduce your chances of having your catalytic converter stolen by 80-90%.

Want to reduce your chances even further?? Here's what else I have done to provide more security at my RV for very little $$$. I added this simple security system to my RV: ($54)

https://www.amazon.com/gp/product/B00OHD15E6
I attached the horn/alarm to my chassis battery. It has some electrical draw, but my chassis battery gets charged by my solar via a Trik-L-Start (http://www.lslproducts.net/TLSPage.html) so it doesn't matter. If you have solar on your coach batteries only, you could attach this horn/alarm to your coach batteries. The horn is quite loud!

I attach one of the motion sensors underneath my RV pointing right at the catalytic converter aiming towards the top cable connections. Doing this, makes it so it avoids any false alarms from animals, or leaves, etc moving underneath the RV. (Note: Sometimes a hot catalytic converter sets this motion alarm off, so you might need to let the system cool a bit before setting your alarm). Now, if a thief DOES decide they want to spend the time trying to cut out my catalytic converter along with all the multiple cable connections, they will certainly trip the very loud alarm system and they will have to leave unsuccessfully. 🙂

I will mount one of the other motion sensors inside the RV (in case anyone breaks in while the RV is in storage or if I'm away from it on a long hike while camping). I also put one of the window/door alarms on my external generator compartment door. I haven't done it yet, but with the extra window/door alarms (or some extra motion alarms I bought), I will likely put one in the large external trunk storage area. We all know it wouldn't take much for someone to pry open a compartment (or use a common key).

Well, I think that about covers it! For ~$100 you can easily add some serious theft protection to your RV and catalytic converter. Inexpensive peace of mind...

Stay safe everyone!

I've experienced it. Our Hybrid TT was broken into. It was in a storage lot. I was driving by one day and saw the door wide open. I went to take a look and noticed the door lock had been pried open. I only locked it, did not put the deadbolt on. It didn't look like anything had been touched. The police thought they were probably just looking for a place to sleep.

I closed the door and put the deadbolt on. A few days later, the Storage Lot called and told us it was broken into again. This time, they couldn't get in, so they broke the window on the door and even tore the metal skin of the door a couple inches. Then they cut the coupler lock off and cut the tether for the fresh water fill's cap. Just for fun, they went to another TT and cut their coupler lock off as well.

So yeah, don't piss the criminals off.

Sorry that happened to you....it sucks!

I'm curious, what did you do next? Did you move your trailer to a safer storage location (harder for the criminals)? Did you do anything to deter future criminals like install motion lighting? Did you just get your trailer fixed and put it back in the same storage with zero changes (hoping nothing happens again)? Or do you now store your TT and just leave the doors unlocked to make it easier for the criminals?

One thing comes to mind here... It doesn't sound like the people who hit your TT were criminals in the sense that they were looking to steal items for profit/$$ (maybe). It sounds like it might have been (as you mentioned) someone just looking for a place to sleep, or do drugs, etc. Or maybe it was kids/teenagers out causing trouble.

I hope they have moved on to somewhere else and leave you alone (or better yet, gotten caught in the act somewhere else). It sucks when people mess with our stuff.

Here in the country I have 4 vehicles outside with the keys in them including my DP. Been that way for years--But that long driveway only has one way out and that little black box on the gate pole will let me know if you choose to come in and I switch on the flood lights--HELLO!

Reducto ad absurdum....look it up if you aren't familiar.

I'd pick option a) and carry insurance.


Yes, my example is intentionally a bit ridiculous to make a point. Agreed.

So the choices come down to "a" and "c".

a) Do nothing except what normal people do (lock their doors, windows, and then just "hope" the odds game runs in your favor forever...)

c) Take some simple, inexpensive, hopefully effective steps to try to tilt the odds in your favor that you will not become a victim of theft by making it harder on criminals to steal from you so they will likely just move on to another target

Consider this....In either event there is damage from a theft AND insurance covers it. So I would rather choose "C" and improve my odds of preventing a theft in the first place.

What it really comes down to is this: For $100 it gives me piece of mind. It also reduces the chances that a thief is going to inconvenience me for 1-6 weeks at a time when I need this RV for personal travel or one of my renters. Either of those could be hugely painful and/or expensive.

To each their own!

Safe travels!

I'd be surprised if it takes that long.

As far as "deterrent"...by the time they see the orange paint and bondage cables, they are already underneath the rig and committed.

Also, if you do manage to annoy them, do they cut something else while they are under to get back at you? Wouldn't take but a few seconds, to nick some electrical or hydraulic lines.

But then I consider the flip side of that argument....Should I remove the catalytic converter ahead of time for the criminal and just leave it on the ground with a thank you note? This way they almost certainly will be happy with me and the chances of them slashing my tires or damaging anything else under my RV goes way down almost to 0%... With that logic, I should also leave me RV external compartments not only unlocked, but open slightly so thieves know they don't need to break my compartment locks or compartment doors....and I should leave my RV unlocked so they don't break a window or door to get in if they want. Should this thinking extend to my other cars and my home residence also? Should I leave my doors unlocked and windows open at my house so that I don't anger a thief who wants to steal from me or harm me? Should I remove the password to login to my laptop in case someone wants to steal it and then they get angry and damage it and decide they want to damage other things because they are upset? Is putting a password on my online banking accounts a bad idea? If someone tries to access my online banking accounts and cannot steal all my money, maybe they get really angry and decide to come and do me bodily harm??

Seems like the choices are...

a) Do nothing except what normal people do (lock their doors, windows, and then just "hope" the odds game runs in your favor forever...)

b) Make it overly simple for any would be thief to walk away with any of your belongings at any time simply because you don't want to upset a criminal so that maybe they don't do any additional damage...

c) Take some simple, inexpensive, hopefully effective steps to try to tilt the odds in your favor that you will not become a victim of theft by making it harder on criminals to steal from you so they will likely just move on to another target

I'll choose "C" and take my chances. Everyone gets to make their own choice. I wish you all the best of luck as I truly hate criminals and I hope they don't steal from you (or me) next.

I personally would never want to have a face to face with a criminal while they are trying to steal from me. That doesn't interest me (even though I'm a supporter of the 2nd Amendment). I don't even want to PERSONALLY cause harm to criminals (...probably mostly because I'd be fearful they or their crew would want revenge). But that doesn't stop me from enjoying hearing about "when bad things happen to criminals" like this...

I'm curious - is the CC on a diesel pickup higher or lower priority for a thief? I heard the CCs on a diesel are less likely to be stolen. But it was never confirmed.

Years ago, we had a ATV stolen during the night while parked at a RV park. They simply rolled it away some time during the night. Harbor Freight sells a "driveway alert" and its cheap. If I had placed it underneath the ATV, they wouldn't have been successful.

Time2cra you are really living on Mars as there has been widespread news reporting from CNN, NBC, CBS, ABC, WP, NYT and other of your that there is a critical police shortage in places like Seattle, Portland, Or, many others etc due to defund the police. You live in a protected little bubble evidently. Get a life and go fishing as is good for your digestion.

It looks like there is a removable heat shield around that converter, so really you didn’t paint the unit therefore the paint should last.

With seemingly an endless supply of easy targets, my hope is that a thief will take one look and move on to another vehicle. They likely crawl underneath a vehicle with just a cordless sawsall in hand as that will do the trick 99% of the time. If they have to fetch another tool from their vehicle (high speed cut-off tool) it adds time. Or, perhaps the cables can be cut with their sawsall in hand. Regardless, it turns their job of cutting just 2 simple and sturdy access spots (right in front of and right behind the cat) into cutting those plus 6-7 more spots (some which require getting above the cat which would be a challenge especially with something as big as a sawsall...I could hardly reach my arm up there to install the cable). All this while a 115db alarm is blasting drawing attention to them.

Yes, given enough time and determination a thief can steal anything. What I have done for less than $100 probably makes it 5x harder for them to remove, 10x more likely they will get caught or scared off by the alarm, and 20x more likely they will simply move on to find an easier target (...at least this is my hope).

Gives me more piece of mind also (which has value). I recently had my RV (prior to this install) parked in front of my home overnight. I couldn't help but worry a little through the night that it (the CC) might not be there in the morning. Now, I'm no longer worried.

If I have any worthwhile incidents (theft, attempted but unsuccessful theft, etc) I'll certainly report back. Let me know if any of you decide to protect you catalytic converter this way. I hope it never happens, but if I ever start up my RV and hear "the rumble" from the exhaust and then I look underneath to see the main pipe(s) have been cut but the cabled cat is still hanging there because the thief gave up or got scared away, I'll be smiling and back on the road quickly.

Good luck all!

Glad you understand NamMedevac. But here we don't live in apartments and our laws and judges are pretty tolerant of protecting ones property, but I understand your reluctance on the left coast. But you don't have to kill or hurt them, the sound of the round whizzing by and the gravel flying is usually enough to make them leave empty handed. LOL
