If you need airbags, IMHO you are probably overweight.
Have you actually weighed the truck and checked it vs the sticker on the side of the door?
Having the airbags just makes it "feel" like you are fine. The frame, brakes, suspension, etc aren't designed to handle all that weight. A properly loaded truck will still ride and drive fine even with a lot of weight, as long as it stays under that GVW. Automakers put a lot of money/research/liability into that weight label on the side of the door. It's there for a reason.
Just my opinion.
Go back to my first post. Note that I mentioned that when I bought the truck, I raised the frontend of the truck and only the front. ANY load now, without the airbags makes the truck sit low in the tail. The bags are merely raising the tail back up so that it sits level when loaded. I am not over loaded.
When I raised the front of the truck, I COULD have raised the rear also but that would have defeated the point of making the truck level when empty.
Normally, I carry about 800 pounds of tongue weight.
I plan to carry up to 1500 with my new trailer (gooseneck) and I still want to be able to level the truck. 1500 pounds will not over load it. It is after all, a 3/4 ton truck.
Diamond pilot,
I haven't gotten the onboard compressor but it's on the list as is a MAX brake controller, and a harness to move the trailer connections into the bed.
I ordered a B&W turnover ball hitch Monday and it is scheduled to be delivered tomorrow. 10/8/08
The trailer I'm getting is a Maxey 83"x16' Gooseneck dump trailer rated at 14,000 pounds.
According to my PRECISE measurements, I can pick up my box blade and put it in the front of the trailer, then load my 3240 behind it with my tiller on,
set the loader bucket on the gooseneck and close the gate of the trailer.
It'll be close, but I think it will work.
