We are new to RV forum. My husband & I have been using the 5th wheel for the last couple of years, only when work slows-we are owner/op under the gun to exist. We think 2 months should be enough time to go south route departing after Mem'l Day for a work/vac stop and returning along the northern route in July. We'd like to see Mesa Verde,Gr Canyon,Zion,Yellowstone,Tetons,Badlands, then come down through St Louis, Kansas City to Memphis and home to Central Florida. We have a Dodge 3500 pu and no genny in the trailer. What are the best routes to follow or "avoid" for this rig? When should we make reservations , for what ares, and best sites to see. I did this route as a youngin' with my parents and wonder what has changed.
