We did the progression thing of tents, pop ups, tag behinds, fivers and dp motor home. Recently we have been seriously considering going back to a fiver. The new fivers have a LOT of room and all the bells and whistles of a motor home. It doesn't really make any difference to us as I have to pull over to go to the bathroom anyway. We always stop for lunch when travelling as well. In 2004 we went cross country with our old fiver and it was very enjoyable.
Unless something happens I fully expect we will be in a brand new fiver in a few weeks.
