Other class b motorhomes floor plans (around 20 ft 11 in, near $56,000), similar in size and price to the Nova 20RB.
What sets the 20RB apart from most Class Bs is that rear bath. It's a genuine dedicated wet bath, not an afterthought, paired with solid hardwood cabinetry that Coachmen rightfully points out you won't find on competing ProMaster builds. The Rockwool R-15 insulation is legitimate: owners consistently report strong four-season comfort, and the Truma Combi Eco Plus handles both heat and hot water efficiently. Three Group 31 AGM batteries and dual 110W solar panels come standard, but the real power upgrade is the optional Li Lithium system, which owners say runs the Truma Aventa A/C reliably for 6–8 hours off-grid. The Ram ProMaster 3500 V6 returns around 20 mpg in real-world driving. Unusually strong for a Class B with this much gear built in.
