The big sister to the Class A RV, this RV is built to last forever. If you are thinking investment, the bus to RV conversion is the best choice. With a safe, smooth and comfortable ride, this conversion has a stainless steel, fiberglass or aluminum membrane. It holds its value year after year.
However, go this route only if you are committed to long term RVing...it being the most expensive RV option. Many are unable to feel comfortable driving a bus and getting parts and a mechanic to service these vehicles might be difficult. Keep in mind as with the Class A, you will need to rent or tow a car once at your target location.
