If they plan to buy the RV their is one big difference in my opinion. When you get home from your trip in a Fifth wheel you put it away and forget it. Mine sits under an awing beside the house and does not even get rain or sun on it. For a Motorhome you still need to maintain the engine, transmission, and other things that cannot sit for six months unattended. My sister has a MH and spend more money on it after it has been sitting unused than when they are traveling. If you get a diesel engine this is even more important. They last longest when used often.
