This forum was a ton of help last year when we took our MH to Cali.
This year we want to visit family in Washington State and to avoid steep grades and narrow, difficult roads by staying on the interstate and out of the mountains as much as we can.
We were thinking going up through New Mexico, the east side of Colorado and Wyoming up to Billings and then West, sticking to Interstates on the way up. We know it's impossible to avoid all mountain driving.
We appreciate any advice and suggestions.
