Just weighed...

The GTWR number is from the Keystone stats. There's another thing acting on the pin weight which I had completely forgotten about. 500 lbs of emergency food in 1 and 5 gallon buckets in the forward compartment with the batteries. Forgot to remove them. Also noticed my water tank is in the rear and it was near empty. More in there would shift a bit of weight off the pin but increase the FW overall.

I will definately look at changing wheels/tires.

I can understand how people can drive around ignorant and happy. Just on feel and ride alone the rig is terrific. It's this forum that got me asking questions to verify what I really have. Thank you all for constructive comments.

GTWR 1980

Was this number derived from actual scale weight not hitched to the truck? It does not appear to be consistent with the rear axle weights before and after being hitched that you provided. For example 6420-3260 is 2980 pounds. Is there other stuff in the rear of your truck and what does the hitch weigh and was it part of the first weigh without the fifth attached?

Also if the math is working out correctly your trailer has 9520 pounds axles weight plus the tongue weight as weighed would be around 12,500 minus whatever the hitch weighs (around 200-250 pounds). Where did the 1980 tongue weight number come from? If it is a brochure or dry weight number don't believe it.

So, put some 18" rims and tires on it. 17" tire ratings are the lowest of the bunch.

275/70R18E are rated at 3640 pounds.

Should be able to find a set of 2013+ 3500 or 2014+ 2500 take offs. Chris

Those numbers are not good.

I wouldn't worry about any trucks GVWR. Hell 99 percent of trucks operating commercially do not use the trucks GVWR to determine axle/tire loads. Nor does our trucks have a sticker GCWR. Weak link/safety issues with a 2500 can be lower rated tires/wheels and no aux upper overload spring pack. Your bags take care of that issue

As other say tires are a weak component along with the OEM wheel ratings. With a 6010 RAWR it does no good with a tire at 3195 and the wheel has a 3050 ? lb rating.
The rear axle itself is the same AAM 11.5" used on the 3500 SRW and DRW trucks so its not the least bit stressed.

If you like the batteries I would upgrade wheels and tires to a higher capacity. Some one will be along pretty quick and say just put 19.5" tires and wheels on your truck...which is a great upgrade. For more input on 19.5" 4000+ lb tires/wheels check out our truck camper forum where its a popular/safe upgrade for 250/2500 and one ton SRW/DRW truck owners who need more capacity.

Yes, OP, you should be concerned. Being over several truck weight ratings, and FW GVWR is not a good place to be. I would at least get FW within GVWR, get rid of some pin wt, removing some truck rear axle wt.

Others are getting by in similar situations, only you can decide if you want to follow that lead. I would not.

This all sounds so familiar. I had an '08 Chevy 2500HD DMax and if the dry pin weight was accurate from the factory, my 5er overloaded my GVWR by #100 just pulling it off the lot empty. Decided to go up to a 3500.

On edit: OP, there are certainly a lot of people doing what you are doing ( It doesn't make it right) but I agree with the posters above that you at least need to be sure that you are not overloading your rear tires.

Rides level, rear tires set for heavy load at 80 psi. Rear tires are as described above, **** it. Unfortunately I replaced 2 12v batteries with 4 6v batteries @76 lbs each. Seems I shouldn't have done that.

OK, let me get this straight. You're 1980 lbs on the pin and the 9030 lbs on the axles, for a total of 11,010 total on the trailer, as loaded; correct? That puts you over your rear axle spec by 230 lbs; correct? Were it me, and the tires were in spec, I wouldn't worry too much about it. You =could= move 2 batteries (or even all 4) further to the rear somewhere, and cut that 300+ lbs off the pin, for starters.

No the OP is 2,980# on the pin, 6,240 - 3,260 = 2,980# + 60# front 3,040#.
So the 5er weighs 2,980 + 9,520 = 12,500#

Plus the 60# on front...5rv weighs 12,560#

Truck has a payload of 2170# (longbed) or 2030# (shortbed)
Passengers Etc of 571# (front/rear axle weights minus base weights)
So payload dropped to 1599#------5vr pin of 2980# is 1381# OVER Payload

Truck has a GVWR of 9600# (vs the 8800#) but you are still 1440# OVER GVWR (11040-9600)

Truck RAWR is 6010# (weighed 6240) so you are 230# OVER RAWR

5vr GVWR is 12,220 (weighed 12,560) so you are 340# OVER 5vr GVWR


1381# OVER Trucks Payload (Longbed--otherwise 1471# OVER if shortbed)
1440# OVER Trucks GVWR
230# OVER Trucks RAWR
340# OVER 5rvs GVWR

But hey.......you are 1440# UNDER GCWR (220000 minus 20560)
And you are 150# UNDER Trucks Rear Tire MAX Load Ratings (6390 minus 6240)

Should also check 5vrs Axle ratings (5200 or 6000) and 5vrs tire MAX Load ratings (you have 9520# on 5vr tires/axles)
