I second the Fummins idea!
Only not on the 99+ bodystyle...I think they are garbage. I can't stand the interior. Crap layout on the door sill- can't comfortably lay your arm on it. Completely $hit cup holder. The door skins are paper thin- you can watch them vibrate when you close a door.
To me, a 92-97 Ford (F350) was the best chassis as far as build quality/stoutness while still having somewhat modern creature comforts (i.e. nice cruise control layout, wiper controls). TONS of interior room, quiet ride...simple build. They don't have as big of frames as the 99+ from the looks of it, but they are still huge.
I guess I'm biased- I wouldn't buy anything new. Too much electronic garbage to work on in 20 years when it all gets flaky. And don't think I'm an outdated hillbilly scared of wires- I'm an electrical engineering tech, so I deal with electronics all day. I know fully well the more things you have in a circuit, the less reliable it gets. Simple statistics. Everything electronic on engines is an add-on to supplement a mechanical function...
