Please post the gist of your lawyer's response once you get it. I would be very interested in hearing what he says.
On a somewhat related note, I hope you are aware that, under Federal law, you can ONLY buy handguns in your state of residence, and nowhere else. If you were to buy a handgun in NV using your NV Drivers License as ID, and then buy another handgun in MI using your MI ccw as ID, you would be setting yourself up for some serious time in Club Fed.
This whole issue of multiple state residency comes up fairly frequently in the mainstream RV forums. Lots of fulltimers would like to claim to be residents of state A to register and insure their Mega Motohome, but also want to claim to be residents of state B for tax purposes,etc
It's almost impossible to do without breaking a bunch of laws.
Or so I'm told . . .
