Heritage Glen 372RD

Looking at upgrading to a new 372rd. Has a gvwr 14,100 and hitch weight 2100 lbs or dry weight 11,150. Will a 2017 gmc 2500 Denali duramax with Timbren SES suspension upgrade be adequate to tow with. The tv has a 15,700 5th wheel rating and a gross axel rating front 5200,rear 6200.
Cheers Rick

Using this calculator, that dry pin weight is likely going to be up near 2,600 lbs:
Estimating Tongue/Pin Weight from Dry Weights - Towing Planner

A bit more or less, depending on how much you pack. Up to around 3,000 lbs if you fill it to the brim at it's GVWR of 14,125 lbs.

Have you ever scaled the truck to compare it against it's tire load capacity, GAWR, and GVWR? My guess is that you'll be over on GVWR but I don't know where the axle and tire weight ratings come into play.

Oh, and hold onto your hat for the onslaught of folks telling you that you're crazy to consider overloading a 3/4 ton truck and a ton of other who say you're just fine with the truck you have.

At the end of the day, you'll trigger a 15-page thread where people get heated and you're nowhere closer to knowing if your truck can (or should) handle that trailer.

Have fun. Get the popcorn ready.

As I understand the truck has a gvwr of 10,000 lbs. Gvaw front is 5200 and rear 6200 so 11,400 lbs. Since the 3500 is the same frame just added springs the Timbren SES can handle 8600 lbs. I had my current rig scaled and 5200 front, 5300 rear and 8900 trailer. The dry hitch weight is 1500 lbs so just going up 600 lbs. The 372rd has an elevated rear living room so massive storage underneath. So my theory is to offset any bedroom weight which will be directly to the pin by stuff in the rear compartments. I don't have a lot of stuff and would only add max 1500 lbs of weight so under the 14 000 lbs gross.

The towing planner that I linked to assumed 1,500 lbs. of stuff added and is fairly accurate.

Any chance you've weighed the truck empty? To know what your unloaded weights are for the rear axle?

No not yet will do before I decide to upgrade or not.

I think it's a worthwhile endeavor to help decide if you should upgrade or not. I'm curious where that rear axle weight rating falls in with what your expected pin weight should be (2,600 lbs. or so).

Rear Axle 3740 less GAWR 6300 = 2560. Now that 3740 includes full diesel some of our stuff, hitch and us. So 2560 is all available hitch weight.
