We have friends that began full timing last year. He towed the 5ver and she followed in the car. This year they bought a Razor, sold her car and bought a small pickup. Now he still tows his 5ver and she follows with the pickup towing the Razor on a trailer. We would not enjoy that, but it works for them. To date, though, they pretty much rotate between wintering in AZ, and seeing their kids in CO, AR and TX. We travel full time all over the country other than our winter 3-5 month stop.
Having the smaller pickup gives them a more comfortable and fuel efficient 2nd vehicle. Of course I understand wanting the 2nd vehicle which is why we FT in a Toy Hauler and have our Goldwing with us. Good luck.
