I am thinking of buying a 2000 F250 XLT Super Duty,7.3 PSTD, auto trans w exhaust brake,RWD, limited slip, tow pkg,rear overload springs, firestone rear spring air bags, 2006 Lance 915 lite, no genie,...
Some people will say the 7.3 is the best Power Stroke. Lighter and simpler than even the 6.7 made by Ford. Yeah, every diesel since ‘94 has been a PSD in spite of them not being built by Ford. :). Look it up or just look at the side of the Ford trucks.
Anyway, as long as you have high rated tires at 3700 or so, I think you are good. Will it be an awesome hauler? No. But, it should be ok for light use. Tongue weight + TC weight is the limiting factor when towing for most trucks.
