GAWR, how close are your to it?
Sorry about yet another thread about weights, but searching the forum, I couldn't locate a specific discussion regarding GAWR regarding operating near the limit. Mello Mike has a good write up about ...

So are you saying you are 500 pounds over your tire ratings. That is usually the limiting factor. My 2011 Chevy 1 ton SRW GAWR (rear axle 7050) is exactly what the tires are rated for. The axle itself is rated somewhere around 11k. When I put my TC on with no water and just me I have about 380 payload left. When I get everything in I will be over a couple hundred pounds and I will still put my boat behind me which has a 250 or so tongue weight on a extended hitch. It still handles very well. I will get heavier duty tires when my present tires wear out. I also only travel at 60mph or less with truck camper and boat in tow.
Here are the specific numbers I'm working with:
GVWR 13,025
GAWR front 5600
GAWR Rear 9375
Tires "E" rated 3085 single, 2835 Dual
Truck with Camper loaded (incl 20 gal. water/stuff, full fuel & pax, without Motorcycle or carrier) 13,150
Above with full water 13,800 (Scale actual front 5040, rear 8760)
Motorcycle and carrier 400 lbs.
With the above tire ratings, I figure the following:
Max front 6170, max rear 11,340.
Looks to me that I'll be at 9160 rear axle with full water and motorcycle + carrier or 2180 under max tire loads for the real duals. GVWR will be (w/ full water) 14200 or 1175 over GVWR, but under on each axle. (Front by 560, rear by 215). Water can be backed down to 20 gals. or less to improve on these numbers.
