Problem solved:
2001 Ford F350 SuperCab XLT
V10 Auto 3:73 rear gear
Power everything with A/C
Has the optional Camper package from the factory
I installed the later model front grille (modified to fit) and clear front corner lamps.
I also had the Line-X spray in liner and bars installed for my RBW 5th-wheel hitch, Magnaflow muffler with stainless tip and the Y-pipe mod/fix.
Truck is not perfect, but it is mechanically in great shape, which is what counts. And for the price, I couldn't beat it.
81k Miles
Drove it home for $9700.00
Set the 3380RL on the hitch at full weight and it never got close to touching the helper spring, LOL. I thing the truck dropped at the most 1.5 inches in the rear.
I also installed a SCT tuner from 5-Star Tuning with three custom tunes, 91 octane Eco-Perf, 91 octane Towing and 93 Octane Performance. Mike at 5-Star tuning was great, they seem to specialize in V10 tuning. I can tell the difference on the Econo-Perf, drives really well. Torque converter locks up in 3rd gear instead of overdrive which helps with the mpg. At the most, 1-2 mpg gain, but I'll take what I can get, LOL.
