The Sportsmobile Promaster RB 164s squeezes a full bath into a compact 18-foot Class B footprint, which is a rare find at this size. The ProMaster's boxy, upright interior gives Sportsmobile more usable conversion space than many rivals, and the front-wheel-drive layout earns consistent praise from owners for its tight turning radius and everyday driving ease. The cab comes well-equipped with swivel seats, a 10.1-inch display, surround-view camera system, GPS nav, and remote start standard, and options like adaptive cruise control and heated seats make longer stretches genuinely comfortable. Owners of ProMaster-based builds frequently report solid long-term reliability, making the Sportsmobile Promaster RB 164s a practical choice for two-person travel without the bulk of a larger rig.
Other class b motorhomes floor plans (around 17 ft 9 in, near $43,000), similar in size and price to the Promaster RB 164s.
