Our travel trailer has a max weight of 7600#. So it seems only the 3 big trucks in the 2500/250 series will cut it. Or maybe something else? My question is, if we are wanting to only spend around $20...
Early build 2007 Dodge Cummins 5.9l would be a great candidate. Especially with the Megacab. Avoid the Ford 6.0l Diesel. This sounds like one long road trip? Duramax in those years would be good. The 3/4 Suburban would be a great candidate.
