I think it's going to be tough to find a 4x4 cheap pickup here. The only ones I have seen a the Mitsubishi w/4 doors and expect to pay at least RD300k and don't expect it to be too pretty by the way. One in decent condition will set you back RD450k or more easily.
It would be great if all of you could advertise in the DR1 classifieds. We have this great board to communicate on .. let's do the right thing and take ads to the classifieds. The rates are very reasonable.
