Pulling a 25ft travel trailer from Southern Calif. to Carlsbad NM then up through Four Corners and on into Utah. Will spend 1 week travelling through New Mexico and eventually end up in Zion where we have campground reservations at Zion River Resort. I just purchased a new tow vehicle so I'm not sure how it will handle some of the grades I may encounter. I think I'm ok until I get in to Utah from the Four Corners area. I would like to see as much as possible between Four Corners and Zion but don't really need the drama of pulling a trailer up a lot of steep winding roads. Thinking of going up through Moab and staying a day or so there. Any help on a good scenic, trailer towing route form the "corner" to Zion would be appreciated.
