Ford F250

By all accounts they ride well despite being leaf sprung, due to the long wheelbase and wide track.
They certainly have plenty of power with a 7.3L turbo diesel V8 but they can be a bit thirsty if you use all the power for heavy towing. Also the HEUI fuel injectors cost more than the crown jewels to replace when they wear out.

Personally I don't like the Ford V8 diesel engine, only because it is a messy looking engine in terms of the way the accessories are hung off the block, an inline 6 cylinder is a lot neater.
Ford used to offer a 4.2L six here but discontinued it a few years back.

I like the auto gearbox though - good for sand and mud!
