me too, but as ford the trucks id go with a 94 older ford or 95?older dodge
as for rubber parts, 99% are just the fuel lines (nothing in the IP)...not a big replacement problem just use viton lines to replace with
"they" say the best is mercedes 85older...can run it on "sand"
basically anything IDI, the newer DI have precision injectors with low tolerences that with succumb to carbon deposits much sooner (1/2 the time) as with pertoleum diesel.
as for the toyota that would be sweet, but good luck finding one...they did make quit a few D50/mitsubishi diesel pickups and i see a few here and there.
