I bought this thing a few years ago to haul various bits of junk around. I had owned this truck three years prior so I had somewhat of an idea what I was getting into again. The truck runs great, but the motor is a little tired and the oil pressure isn't real great anymore.
Never failed to get me where I wanted to go. Took it on many a long trip with nary a trouble. I got it stuck a couple of winters ago and the poor transmission decided to throw in the towel. Seemed like the gears were stripping out. I left it sit over winter and got it out the following fall. Truck started and the transmission seemed to had self healed itself. Or so I thought. It was good enough to make 4 two hour trips on the interstate before deciding enough was enough. Still got home though.
The 300 six and three on a tree combo was good for at least 20 mpg, although I usually got right around 23-24 mpg. I know people with compact trucks that get the same mileage. It wasn't real fast, but would cruise (not happily) at 75 for hours on end. It is more of a 55 mph type vehicle.
The biggest thing this thing had going for it is that parts cost next to nothing, and just about every auto parts place has stuff for this thing on the shelf. Also this thing is extremely simple to work on. Very bare bones, no power steering or power brake setup to go out. I would recommend that if your mechanically inept but still want to save a little coin, this truck would be a great way to get some car fixin' skillz. Plus rebuilding the whole truck probably cost less than a new Honda Civic fuel pump (slight exaggeration). I also ignored a lot of problems on the thing as well. Easy fixes those kind are. Unlike new cars, one can ignore stuff going bad for a while because the parts are a bit beefier and take a lot longer before they fail for good.
Truck has gotten to the point where even if I put a new transmission in it, the frame is too rusted to be trusted. Bought another frame and transmission so hopefully I'll be ready for more adventures.
