I will not argue the virtues of the motorhome versus fiver - - you probably all ready know most of them. This I will say - - when I had children that traveled with us, we had a motorhome. When they left the nest, I immediately sold those clumsy, expensive, always breaking, time hogs and got a fiver. I would not go back to a motorhome.
With kids, I would never try and travel with a fiver on the long trips we did with them. As stated, there are some nice floor plans in motorhomes for multiple sleeping and you don't have to go all that big to get them. Tiffin makes a lot of motorhome for the money. Mine was the best of all our motorhomes. Sorry I didn't stick with them on the last two.
