dt466 gvw is too high. I have to keep the combination weight between the truck and trailer below 26,000. I just found this . However, not sure if it will be reliable enough. I just don't want to buy a piece of junk.

I towed that trailer full of logs with a 3/4 ton p/u up a few big hills at 40 MPH. It would easily get up to 50-60mph on the flats. It actually tows really well. The 3/4 ton was a gas 6.0. It was just a little squatted for my liking. I think a dually will help with that.
I like the idea of an older truck because less issues with computer crap. The craigslist one is a 6.5 liter diesel, that cold work. Also, I am not driving to Alaska everyday. I work about a 30 mile radius. With lots of drop spots for the logs. Everyone around here in Vt and NH wants wood. After last years winter this stuff is gold right now. Even spruce, hemlock and pine.
