Montana RV Registration Fee Calculator

RV registration in Montana splits by type. Self-propelled motorhomes register like other motor vehicles — motorhomes have their own age schedule: $282.50 under 2 yrs, $224.25 to 5 yrs, $132.50 to 8 yrs, $97.50 after — with a one-time $237.50 permanent option at 11+ years and an $800 surcharge for coaches over $300k MSRP (2–5-yr rate shown). Towed travel trailers and campers run on a separate schedule: roughly a one-time $152 permanent registration. Travel trailers register once, permanently, by LENGTH: $72 under 16 ft, $152 at 16 ft and over. Because motorhome MSRPs are large, value-based charges hit RVs harder than any other vehicle class.
