howdy there,
I also have a diesel rig alot like wardens, and they are work horses, slow on the get-go but are pretty much bullet proof. haven't had any major issues but rice burners getting under foot. I tow alot of cars & trucks with my tow-dollie no problem. only thing that sucks is mine is a c-6 so I only have 3 gears . but does tow well at 60-65. hope that helps. might want to read threw the dieselstop.com for more info on fords new and old.
