With a rig that is 26-27 feet long you can have a rear bedroom with
RV Queen size bed and won't have problems getting into and out of the overhead bed that some with arthritis have. Sleeping on the convertible dinette cushions or jackknife sofa is not pleasing for many. Many RV'ers just love their 22-24 foot rigs, many trade up to a longer rig to get a rear bedroom setup. Short rigs also have little cabinet or other storage space. Your type of RV usage somewhat determines the length and floorplan/features you will want/need.
