30 Amp Fuse Question

Hey, y'all. Me again with a newbie question. So far y'all have helped me solve the mystery of my outdoor kitchen as well as my DVD player so I'm hoping you'll help educate me one more time. In a few years, I hope to return the favor to another RV newbie...

So, I have a 2015 Cruiser RV R24BHDS travel trailer. I bought it brand new a month ago. I have had it for four weekends now and I have camped every weekend. Love it. Absolutely love it. I have been a long time tent camper but now with a 3 year old and a 1 year old I'm appreciating the fun the camper offers.

Since owning my travel trailer I have blown the 30 amp inline fuse that is beside the battery twice. The first time I blew it was during my first week of ownership and I thought very little of it, mostly because I'm new to all this. Switched it out and no more problems... Today, the same thing happened again so that got me to scratching my head. In both instances I have been running off of battery power and pulling in my slide. I'm thinking now that maybe I should get in the habit of making disconnecting from shore power be the last thing I do when taking down camp... but that's neither here nor there at the moment. I've pulled the slide in and out at least 20 times at this point between setting up, taking down, and then cleaning up at home... Only happened twice.

I checked out some basic stuff and learned a little about RV electricity as I went. I put a meter to the power converter while hooked to shore power and got a reading of 13.46 volts, which is what the manufacturer of my converter (WFCO 8955) says it should be... I disconnected from shore power and read with only DC and got about 12.5 volts, so the converter seems to be just fine. ...Well, at least based on my 1st grade level knowledge of electricity...

I checked all of the other obvious stuff too... Couldn't see any obviously pinched wires, any bare spots on wires touching screws, the frame, etc, etc... Nothing. Doesn't mean that isn't happening somewhere, I'm just saying if it is, it isn't in a spot where I can easily see it.

Now, the very bottom line is that my trailer is a month old and I have a warranty. I could just tow it back to the dealer and let them figure this out. If I can't figure it out that's what I'll do. But with the aforementioned 3 year old and 1 year old time is a very valuable thing and hard to come by! The dealer is about an hour tow.

I'm wondering if you more seasoned folks see something I'm obviously overlooking or even doing wrong. Are those slides designed to be pulled in and out when using just battery power? I just assumed they were...

Thanks for the help! Sorry for the long post!

I had/have a similar issue with the slide out on my 2015 Roo. Took it back to the dealer and they replaced the 30 amp fuse with a breaker. I have yet to test it but will.

Mine would blow the fuse pretty much when getting to the point of fully extended or fully retracted. (never got to the point where you hear the click click click of the slide out).

Take it back to the dealership. This is a very common problem with Cruiser RV, as is a lack of quality workmanship. My 2014 S280QBS (bought May 30th/ 31st, 2014 and sat in our driveway until mid-October 2014) had numerous workmanship issues and were actually nothing compared to others. The worst thing was we had a roof leak and didn't realize that there was a problem with the roof until 2 months after putting it in the shop and one month after the warranty expired. Guess what we were told? There were gaps in the caulk. We didn't report it within the first 60-90 days and it was our fault for not having the roof inspected every 6 months. We picked it up after being in the shop for two months and headed out to my family reunion (repairs weren't finished---due to waiting for parts from CRV, or so we were told by Vogt). Within 75 miles, my husband saw a blanket flapping from the trailer, except it was no blanket, it was our roof. This happened in July 2015. Called the service advisor from the side of the road and had to cut large chunks of the roof off because he was afraid it would come completely loose and cause a traffic hazard. Our 7th RV, never had problems of this magnitude with any other trailer, even the used ones (only 2- all the rest were new). Seriously document, document, document. Wish I had found that out sooner... both the dealership and the manufacturer told me to file it on my insurance.

Google "Cruiser RV complaints". There at least 8 complaints on one BBB site, not to mention other forums, you.tube videos and Facebook.

Yep, my bad. Made Biscuit blow a fuse, too. :C

Still think it's most likely a simple battery/usage issue.

EDIT: To the OP: If you've not done so already, you might want to check out the Fun Finder Owner's Club Forums. Even though it's for FunFinder owners, there's alot of information relevant across the CruiserRV brands.

What does this have to do with a 12VDC fuse blowing?

Someone seemed to be asking why 10ga wiring was used.

Battery voltage shouldn't have been low... but I'm speculating. It had been plugged into shore power for two days and only "unplugged" minutes before, so I'm assuming the battery should have been charged if everything is working correctly.

But 12.5V IS a bit low for a fully charged battery.

I'd suggest to keep an eye on your battery. You don't make mention of what you're doing when the TT is in storage but if the battery is connected to the TT and allowed to sit for a couple of weeks, it will be dead. Do that a few times and your battery will be a goner. Some folks either pull off a battery cable or install a disconnect switch for storage. Some also leave the TT plugged in with the converter charging.

Thanks! I will absolutely keep an eye on it for sure. My TT does have a battery disconnect knob, which I use while the camper is stored. Hopefully that helps...

I really do appreciate all of the help from y'all...

I think at this point I'm going to leave well enough alone. I've pulled the slide in and out several times in the last couple of days off of battery power only with no problems. It is very possible that I had "too much going on" when I blew the fuses. I had used the jack, had lights on, etc. Maybe that just did it... If it does it again, I'll take the effort to remove the underbody protection and trace the wires to the slide motor. I can look for anything loose, pinched, etc. If that doesn't do it, I'm going to consider it above my pay grade and take it to the dealer and let them wrestle with it since it is under warranty.

If the latter becomes the reality, I will make sure to come back to this thread and update with the problem and subsequent fix in hopes to help some other half-clueless newbie. ;-)

Along with the advice and troubleshooting, I really appreciate the patience. I'm learning as I go... but I'm learning!

Happy Labor Day camping...

50A wire is 6 gauge.

10ga wire is going from battery to slide out motor with a 30A in-line fuse that has blown 2X on OP when operating slide out on battery power only.

That is ALL this whole post from OP is about.....slide out motor 30A in-line fuse blowing........and WHY!

I double-checked the ampacity chart.

#10 THW/THWN copper is rated for 30a
# 8 THW/THWN copper is rated for 50a
# 6 THW/THWN aluminum is rated for 50a

Thanks for getting me to look that up....I was not correct.

let's not start talking about temperature and line drop.
