I don't think the diesels have much more on the rear axle and they share the same spring pack so it should be comparable.
Just to clarify... I'm not trying to add load carrying capacity. There is plenty of payload and rear axle capacity for our rig. I just want to know if I'll need something to help level out the truck when it's hooked up. Don't want to be sagging too bad in the rear since the truck only has 1/2" of rake to it unloaded. My F150HD started 3" high in the rear so it could squat a lot before it looked funny.
