Im about tired of payin this new truck payment so I think im going to go back to a late 90's F250 Diesal. Ive seen several in my price range but Im worried about buying one and it needing serias work as soon as I get it. So what is a lot of miles for these things, do the trans have any chronic problems (last used truck I bought blew a tranny after a week and a half, ended up costing half what the truck was worth) and what kind of stuff should I look for when buying one? oh yeah, and about what kind of fuel mileage should I expect to get out of this thing? Thanks for the input yall.
