I will be driving from Washington DC to Seattle in early June. I'll be doing all the driving as my 2 road trip companions will be my dogs. Will be driving either a 10 ft. or 14 ft. Uhaul truck and will be towing a small convertible. Planning to do the trip in 6 days. Looking for the fastest and flattest route. After taking 76 through PA and then 80 towards Cleveland, I'll plan to take 90 towards Chicago.
Then my question is, do I just take 90 all the way to Seattle or should I take a more northern route through MN, ND, and MT on 94 and then jump back on 90 in Billings? I've read that 94 is flatter, but not sure if it's worth the extra distance. Any thoughts?
Any motel recommendations for basic, inexpensive places (but not fleabags) not far from the highway that accept dogs would be greatly appreciated. Don't need anything fancy; just a place to get a decent night's sleep so I can get right back on the road the following morning.
Thanks for any advice you can offer! I've never done a cross-country trip before.
