Here's the thing:
Other than dual rear wheels, there's generally little difference between a SRW 2500 and a DRW 3500.
Rear end - same (may have different gearing, but you can swap gears to make them the same)
Brakes - same
Axles - same
Suspension - same, except for an overload spring or two, which can be easily remedied as well
The "litigation" issue is classic.
It's silly to imply that my insurance company won't cover me if I'm 1,000 lbs overweight, but will cover all damages if I get drunk, drive 100 mph and crash my car.
Years of these litigation posts, and not one shred of evidence.
This site even has a moderator who was an insurance adjuster who states its hogwash.
To close my rant...
GAWR's are assigned for the tires/wheels the truck came with, and the intended use of the truck. For example, my truck has a RAWR of 6,200 lbs from Dodge. Duallies are rated higher...yet AAM gives this exact same axle 11.5 a GAWR of 10,120 lbs.
Exactly.
SRW and DRW have the same axle - rated at way more load than any pair of tires you can buy. The limiting factor is the wheels and tires. jbee's SRW came stock with 3100# tires, hence the 6200# rear axle cap on the sticker. Switch to Class E tires rated at say 3640# and you've increased your rear axle capacity by 1080 lbs to 7280#. (Your GCWR WON'T increase!) Add your airbags to level you out and save your springs and pinion and you'll be fine. You may even be able find some 10 plys in your size rated at 3750 lbs per tire.
My truck and TH weights are nearly identical to jbee's setup.
