The Real ID Act, if it ever is implemented (currently delayed), will cause problems for Full-Timers. The biggest problems are vehicle and drivers licensing, and determining a "residence" state.
For vehicles: I have seen 18 wheelers rolling around with something called an "apportioned" license plate. Well, why can't full-timers get something similar to that? Have each state sell a special uniform license plate for "full-timer" RV folk. This plate would cost, say, $76. Of this $76, $1 would go to the Federal Government (Dept of Homeland Security? Just playing with ideas....). Of the remaining $75, each state would get $1.50. Ok, there would be some bugs to work out, for example, should Hawaii really get a share of this, because...... can you theoretically expect someone to "drive" to Hawaii? Ok, counties would lose revenue on this one..... Still gotta work some bugs out.
Driver's Licenses: Just pick a state and stick with it. But, since the Real ID Act is trying to lean us to a "national" ID card (which I'm vehemently against!!!!), well, have Dept of Homeland Security issue a "national" Drivers license. Again, split the revenue among the 50 states. Ok, counties might lose revenue again.....
Residence: With the recent flap over (I forgot the name of the county) in Tennessee that refused to let someone vote because they "didn't have a connection other than a mailing service...." Well, here is a compromise. Each state have a special "RV registration." On this one, you just, well, admit you don't care about "local" elections. You vote only for STATE elections. It would be an "at large" voting registration for that state. This way, you get around any "connection to the place" issues.
So, what would be wrong with these ideas? Or let's come up with alternatives if these ideas don't work!
