Class A RV
Step up to the prestige plate when you drive a Class A RV. Think rock or country music star, with a large bus like appearance. The Class A is very safe (making insurance cheaper) and financing is easy to get.
These RVs have all the conveniences of a home, with complete kitchen and bathroom facilities. While mom or dad is driving, the kids can be "in the house" reading, watching TV or taking an afternoon nap, all the while air conditioning or heating controls the temperature. A massive fuel tank keeps you going about 500 miles between filling station stops.
Driving is more stable and easier than the towing involved with trailers and fifth wheel options, but if you are thinking mountains or bumpy terrain this vehicle is not for you. And if you are going to do any driving once you reach your destination, you will need to tow your car or store away a bike.
