Rte 212 from Rapid City to Garryowen

I have traveled US 212 a week or so ago. I see no reason you would have any troubles. I picked it up at Alzada, left it at Broadus

There are gas stations along the way. Some mountains but not bad and there is sometimes space to drop the camper while you go through little bighorn battle ground if you have time. Not much services or cell phone out there.

Thanks for the info, very helpful.
