Hey Buchanere, welcome to the forum. The Teton 5er is one of the heaviest on the road. You can probably get by with one of the newer (05/07)1 ton diesel dually's pulling a 34 foot Teton, but if it were me I would opt for a mid-sized truck. Maybe a big mid sized GM Duramax /Allison. Normally I advise to go with the Dodge CTD, but I'm not sure if they are making the bigger mid sized truck yet. I think they are, but haven't checked lately. Been too busy RVing down the road.
