I have a 1999 F350 with a 7.3 diesel engine.The gvwr on it is 11200.I have a 41 foot toy hauler and the gvwr is 18100.Is their anyway I can install a airbag system or put some bigger springs on my truck to bring my gvwr up on my truck? Thanks

You really can't change the GVWR with springs or bags. You only change the ride height under load.How much does your truck lack in GVWR for carrying the pin weight plus cargo/passengers?

I think you are misunderstanding the numbers...?What is the available payload for your truck and what is the weight pin weight of your 5er?To answer your question though, there is nothing you can do to change your GVWR. Air bags will upgrade the suspension portion, but you still have to worry about braking, axle weights, tire weights, etc etc.

If you've got 7000 lbs of pin weight, that's 38 percent of your trailer's GVWR. At 25 percent, your pin weight would be around 4500 lbs. At 22 percent, it would be around 4000 lbs.You should visit a CAT scale and get some accurate weights, with and without the trailer.Check the GVWR on the truck, weigh it, and see what you've got for payload.Air bags or supersprings, may improve the ride and stability, nothing will increase the ratings.

My 2004 F350 GVWR is 11,500# and weights 8,000# (with us in it) so I have a 3,500# payload. If you look at the axle and tire ratings you could probably carry more. Legal is based on tires and axle ratings along with what it's actually plated for.A GVWR of 11,200# I suspect you have the 4x4 version.18,100# x 20% = 3620# pin. It will be a little lower is the trailer is not loaded to gross.
