Well, I ended up purchasing a 2nd gen Isuzu Trooper yesterday. I'll build a storage/sleeping platform for it and use it for the rest of the summer/fall to go camping with my gf... I needed something right now and luckily enough the truck seems in very good shape. I'll of course keep an eye on finding a suitable 1st gen Dodge Cummins in the long run. This way I can take the time to wait for the right truck (manual tr, 4x4, my price range) to come along.
