I searched some old threads and have gotten some good information. I knew the gearing was going to be a problem for me. I’m used to driving fast. I just drove about 200 miles at 65 mph with my 1 ton. It seems to be doing fine, but I probably took a few years off the engine. I was told it is the original. I’m also interested if the fenders and grill are interchangeable between a 3100 and a 3800?
