We have a 2007 5291 on 2007 Ford chassis. When weighing this vehicle, we found the rear axle weight to be close to the chassis limit
(9,450 GAWR)with full gas tank, and full fresh water.
Upon contacting GS, they had us return unit to factory. They moved the generator to the front cargo area behind the passenger seat. This removed 300 lbs, from the rear axle, allowing us to have adequate storage capacity in the rear and eliminating the rear end drag at driveways, etc.
We also now can drop tire pressure to 70 lbs. providing a softer ride without damaging tires.
We also had Billstein Shocks installed......improved handling tremendously.
