It costs about 1200 to 1500 to set up a Montana LLC. Montana has no sales tax on RV's. You will pay a one time fee of about 300 bucks for a permanent tag, and then about 200 per year to maintain the paperwork for the LLC. Those numbers are from rememory, so they are estimates.

I am not going to comment on whether this is a good thing or bad thing. You can research opinions on RV.net about Montana LLC's.

The loophole is this. You typically have thirty days to register a vehicle in a state. So, technically speaking, you should leave the state every thirty days to restart the clock.
