I would not have any RV without a dedicated full time rear bedroom with an RV Queen sized bed, preferably with access on both sides and at the foot. You normally have to have a minimum 27-28 foot rig to get a rear bedroom. You will also get much more storage space in cargo bay and in cabinets which may come in handy for near full timing. If you intend to park in driveways or other limited space areas, you may need a shorter rig. A Road Trek B van conversion is better in city traffic but not great for living in or parking in really small spaces.
