Whoa!!! Somebody made a booboo. The road to the Badlands would be I-90, not I-80. Whew!
In 2017, we left North Idaho on May 15th heading to Alaska. The weather was just beginning to turn nice, but some mud on the roads from the oil companies in Canada. The lower Canada roads were a little short on "pull over: spots, but once we got higher toward the Alcan, more places appeared to stop for the night.
It took us a week to get to Tok, about 2600 miles from home. You have about twice that distance each way. When you drive to Ak, you have to go through Tok each way--nice RV places with wash racks to clean the goop off the rig.
We used a credit card for gas purchases, which got the best exchange. Canada means higher prices for everything.
We installed Rock Tamers on the truck, which helped the front of the trailer, but they really threw the gravel to the sides. Also put in a screen in front to the radiator, but never needed it. Never had any damage from driving or other drivers.
Stop often, visit museums, absorb the culture, got to the zoo south of Anchorage, visit Homer, Seward, Denali, & Fairbanks.
The BEST RV trip ever.
The cost ran about $1.00 a mile for everything---$7,000 total. This included a Halibut trip, some eating out, some RV parks, Denali bus trip, ice cream, and a stop at the Salty Dog.
