I had my lance Lite 915 on a 2001 F250. It had add-a-leaf springs in the rear and a front leveling kit. I added an upper overload, rear sway bar, upper and lower Stable loads, and took an inch out of the front leveling kit. Ran it for a year like that. Handled great, especially after the sway bar.
I bought a new truck, a 2005 F350 Crew Cab. Went on one last camping trip to the Deschutes in March. I went to transfer over the rear Stableloads, and found this:
I got the old truck all cleaned up, broken AALs removed, camper tie downs, Stableloads, and Superhitch moved over to the new truck. The Crew Cab suits the extended cabover better. Also, the F350 springs are rated higher than the F250 springs, and with the Stabeloads hooked up it only sagged 1.5 inches.
