Route from Great Falls to Billings

[PSU_fan]

We are driving a 40 ft RV with toad and wondered what route 87 is like, or what route would you suggest? Thanks

Thanks to all of you!
We followed mowermech's route and found it to be a very good route.

I make that trip frequently (we have a daughter and SIL and three grandkids in Great Falls), plus it is the nearest commissary/exchange.
I usually take 87 to Eddie's Corner, then 191 South to Harlowton, 12 to Lavina, and State 3 to Billings. I have done it in our Class A, towing the Jeep. No problem.

By the way, it is Lewistown in Montana. I think Lewiston is in Idaho.

Go for it folks. Absolutely no issues on this route for your 40' rig.

Highway 87 through Lewiston and Roundup is one of our favorite prairie drives we've ever done, some really beautiful country. While we never did it with a Class A, it was no problem with our 36' 5'er and I would hesitate to do the drive with our new 44' Class A

Been there, done that. No problem.

I have traveled from Glendive to Great Falls, it is quite scenic. You won't have any problems. Lewiston is a neat town.
