I live in Texas and have owned 4 motor homes.I did the Montana LLC on 2 coaches and paid the sales taxes for Texas and county on the other 2. Texas is cracking down on the Montana LLC plates if your residence is in Texas. The fines are steep and there is interest tagged on to the fine. If you go with the Montana LLC get your tow vehicle registered in Montana. The difference between tags is a tip off for the DPS in Texas. Good luck and good hunting.
We met Floyd at Donnie Myers in August. He is originally from Ft. Worth. You will like your visit to Donnie Myers. Good facility, plenty of inventory, and good people. Enjoy your visit.
