Lightening tongue weight

I have the ProPride and I leave the tongue weight at 10% (I have a tongue scale). Nothing goes in the TV except people or bikes for a short ride (otherwise they too go in the trailer).

I'll buy a better TV as soon as I can but not for the next 5 years or so :(

Well, you are right to some degree. I was a little too specific when I stated warranty work only. I meant more warranty than safety related, my mistake.

Obviously the manufacturer wants to keep warranty repair costs down. Having lower payload and tow ratings helps keep them from fixing a lot under warranty.

Manufacturers also want a good reputation and want people to continue buying new vehicles. Keeping those ratings below the true actual rating helps with longevity... hence why manufacturers derate engines.

Manufacturers want to reduce liability. If they know the failure point is 100 lbs, they want a nice compromise between longevity, ego and failure. If that means they rate that piece at 60 lbs, they know they are way below the failure rate and it would take an obvious excess of 60 lbs to cause failure. They want to be able to prove that they rated it so far below the failure rate that it couldn't possibly have failed due to the manufacturers negligence.

I misstated my point by saying WARRANTY ONLY. Either way... its not a SAFETY ISSUE.

By the time you have called in “expert witnesses” to justify your position, all bets are off. Good luck trying to show you were or were not "within spec." Add to this other factors like quality of brake shoes on the TT and TV, the stability of your particular towing combo or how well balanced your TT load was front to back and side to side and you will discover; that is what your lawyer is for.

Most people just want to know how well their TV matches their TT. Several will find that they are probably at or a bit over the limit, based on their best guess.

Even the so called experts hedge their numbers. Ford’s tongue weight data indicates a 10 % of TT weight others say 12 or 13%. Some claim WD hitches transfer 15% others as much as 22% of the tongue weight to the trailer.

Even if you weigh your rig on the scales you can easily get a 200 lb. shift due to TV gas tank level and TT water and other changing loads.

In the end, people have to be within their comfort zone, and we know that comfort zones vary quite a bit.

These ratings are for warranty work ONLY.

Gdetrailer is right on this one. The ratings have more to do with liability, longevity, and certification than warranty claims. The manufacturer's engineers know what the absolute limits are for a vehicle and know what's the safe operating limits are for each component. That's something that you cannot say with any certainty. Whatever number they decide has legal ramifications for them. If you snap an axle and take out a school bus of children then it's the manufacturers duty to explain why the design failed while within the safe operating limits. Warranty work is nothing when you compare it to the hundreds of millions of dollars that has to be paid out in a wrongful death suits. Not to mention how bad they would look in the court of public opinion.

If you're in the same situation while overloaded then it's your duty to explain why you can exceed those limits. T plaintiff will call the manufacturer's engineers as an expert witness and they'll gladly show up. They don't want anyone thinking they are to blame. They'll show up with real numbers and actual data setting you up for a big "oops" moment. Even if you somehow come out victorious, you're still on the hook for thousands of dollars in legal fees to just defend yourself.

The manufacturer still has to build a vehicle that will comply with FMVSS. You may be able to overload your vehicle by a ton, but good luck trying to get it to pass FMVSS.

They also have to specify limits that will account for vehicle longevity to it. What good is setting high limits if the vehicle is toast as soon as the warranty is up? Seeing tons of their trucks parked on the side of the road doesn't make them look.

Those limits are in no way absolute physical limits. However they are limits that the manufacturer has deemed as safe. Once you exceed those limits then you've taken on all the risk yourself. I have ran grossly overloaded several times in the past, but I completely understand the potential consequences for doing so.

Oh, so the 10% hitch weight rule of thumb has been transformed into a 12% ruled of thumb by the weight police. Sorry, I must have missed the memo! All this time I'd thought that the 10% rule was a good one. We'd better sound the alarm to all those Europeans who tow with small cars and 5%- 8% hitch weights (they do keep their speed down, but somehow manage not to kill themselves even without sway control hitches).

Yes, an AGM battery could be used inside. Optima is considered a good brand. I didn't suggest it because the OP already had two good batteries, and not everyone wants to junk a perfectly good battery to buy a new one.... maybe even two, since I'm not sure how the AGM and the lead acid battery will do when charging them together.

No... manufacturers stamp the ratings that they will stand behind for WARRANTY work. Safety is not as simple as heavier frame and bigger brakes. Having a dumbass drive a Kenworth pulling a 1,000 lbs trailer doesn't make it "safe". On the other hand, having a half ton driver pulling overloaded with 50,000 miles of experience and defensive driving ability is likely safer than the Kenworth.

These ratings are for warranty work ONLY.

I have loaded over a ton of gravel in the bed of my Tundra with a 1500 lbs payload rating. I've done it multiple times. My truck handled fine.

Toyota claims that I can tow a 10,000 lbs trailer. Therefore Toyota believes that between my brakes and the brakes in a properly equipped trailer, it will stop a total of 15,000 lbs. Now, my new trailer will have 3,000 lbs of cargo carrying capacity. So, instead of carrying that 3,000 lbs in my trailer, suppose I put an additional 1,000 lbs in the truck bed. My combined brakes are capable of stopping 15,000 lbs. My truck, trailer and gear in the bed weigh 13,000. How is that unsafe? Its still 2,000 lbs BELOW manufacturer ratings... its just distributed differently.

Then engine and transmission don't know where that weight sits... they just know they are pulling it. Same with the rear axle. No safety issues there.

The brakes don't know where the weight sits... they are just stopping it. I would be below my maximum approved weight limit for the braking system.

My Tundra with an additional 1,000 lbs in the bed now weighs as much as a 3/4 ton truck, so it shouldn't be "pushed around" by the "tail" of the dog. No safety issues there.

Perhaps long term towing like this will eventually bend the frame... but if you tow 3,000 miles a year or less, I would imagine it takes a LONG time to bend the frame. But, suppose the frame bends... what is the SAFETY ISSUE here?

Lots and lots of half ton owners overload their trucks and don't even know about it. These weekend warriors believe the RV salesmen that they can tow anything on the lot. You don't see or hear too many stories about catastrophic wrecks. My insurance company didn't substantially increase my insurance rates because I tow. Seems to me that if half ton trucks towing RV's were involved in so many accidents that my rates would be higher.

Listen, I agree that towing over your ratings will likely cause faster wear and tear on your truck, but I see NOTHING to substantiate the safety issue.

Safety is more related to the driver and his/her abilities than simply the vehicle. A Ram 3500 dually rated for 30,000 lbs driven over the speed limit can be much less safe than my Tundra rated for 10,000 lbs driven at the speed limit and with appropriate defense driving skills.

All that being said... DO NOT REDUCE YOUR TONGUE WEIGHT BELOW 12-15%. Too light of tongue weight is the easiest way to lose control of your trailer. I would rather drive a truck that is 500 lbs over your GVWR than pull a trailer with too light tongue weight.

Yes, I'm getting that message! We have a truck scale in town, so that's where we did our weighing. I printed off the instructions for weighing and we stopped by there on our way out of town on our maiden voyage. And of course the scale guys know how to do it.

So we won't be reducing our TW. Thanks to all for the advice.

Margaret I understand you are new and seeking advice. I will be blunt with these comments.
Removing tanks and or battery to lighten tongue is a bad idea.
The easiest way to create instability and induce sway is to lighten your tongue.
Unless you know what you are doing you will be making a huge mistake.
Are you using a Sherline tongue scale to verify your moves and taking test rides?
In short reducing your TW is not a solution.Instead it is a recipe for disaster

AGM sealed batteries can be safely used inside, and the price of AGMs is declining. Costco or Sam's Club has some AGM golf-cart type 6V batteries at pretty reasonable prices now.

We have a 15% tongue weight with two 6V standard golf cart batteries on the tongue (~120#). I've been thinking of replacing them with AGMs inside further back toward the trailer axle. Since I also want to double our battery capacity (and weight) the net effect on tongue weight will be about the same, but at least it will not be much worse!!

Personally, I prefer a high % tongue weight for stable towing. But it definitely does put a dent in your tow truck's payload.
