So my husband, my daughter and I will be driving from Seattle to Detroit this August. My husband has a 1986 F350 Utility Truck that will be towing a 35' Travel Trailer.
Flat lands - No problem.
But his truck struggles uphill, and downhill curvy roads are just a little scary towing that much weight.
I'm looking for the best route to get cross-country while avoiding uphill/downhill. Basically the best way to get through the mountains.
Time isn't an issue. We are planning on making a 2-3 week trip out of this.
Thanks in advance for your help!
