    Default Indiana to Grand Canyon and Parks in Utah

    My wife and I are planning a trip from Indiana to Grand Canyon and Utah and we will be pulling a 34ft fifth wheel. I was wanting some advice as to route we should take either I 40 to Flagstaff then to Grand Canyon or I 70 to the parks in Utah first then to Grand Canyon. I'd like to avoid grades sharper than 6%. Any suggestions.

    Welcome to RTA!

    Unless your tow vehicle has a turbodiesel built in the last 10 years or so, I'd recommend you stay off I-70 west of Denver. Maximum grade is 7% but it's over 10000 feet altitude.

    It is not a diesel. What about I 70 from Green river to I 15?

    That stretch isn't bad but there are no services whatsoever and no cell coverage between Green River and Salina, that's 108 miles.

    Towing that kind of load with a gas engine (unless it's a Ford Ecoboost) is going to be rough due to the altitudes everywhere out west. If you only have a 1/2 ton truck that makes it worse, you have too much trailer for the truck.

    It is a 2500HD, I've pulled it in 5000 ft elevations and got along ok, but never in upper elevations.
