Of course do it legally and follow the rules!!!
Our State Patrol offers incentives to turn in your neighbors for illegal plates, so... I am very Legal about it...
There are plenty of ways to do this legally, but parking it in your 'Out-of-state
primary residence' would not be too smart OR legal.
But... say the expensive wheels lived at 'boarding school' in a tax free state...
You do want to be smarter than the average bear, if you are into this 'camping / RV thing.'
