I have a '73 D100 ClubCab Adventurer longbed... 318/727 that has served me well for a few years and is in great shape. I'm finding that I need more to be able to pull a larger travel trailer of 5th wheel.
I am either going to sell this one and look for a B250 or B350 conversion van, or a D250 truck.
To beef up the D100 would be one thought, too. are the D100 and D200 frames the same? Just different springs, axle, and spring hangers in the rear?
