We have a class A. It's actually a 1982 restored vintage diesel Bluebird. That means cheaper tags and cheaper insurance. We pay $32.00 a year for tags. Most counties don't look at value, they look at the year built. With cars that goes hand in hand, but most counties don't have a clue what the value of an motor home is. Our insurance is through USAA so it's very reasonable. That too is cheap...about $100 every 6 months.
We chose the Bluebird specifically for safety. It's metal, not plastic. They are, by far, the safest bus on the market. The engine will run forever. We do have seatbelts that are original. We love it...it's fun and traveled with our little ones who loved it and my elderly parents. We even lived at the beach in it for 4 months. The kids still remember that summer as one of the best we ever had together as a family. Campers and RVers are a throw back to a simpler time. We have kept friendships for years from our travels. If this is something you want to do, go for it. I don't think you'll regret it!
God bless!
