Hawaii RV Registration Fee Calculator
RV registration in Hawaii splits by type. Self-propelled motorhomes register like other motor vehicles — motorhomes use the same weight formula; coaches over 10,000 lbs cap the state weight tax at $300 flat but county rates still apply. Towed travel trailers and campers run on a separate schedule: roughly $329 per year. Weight taxes make Hawaii brutal for RVs: $46 state fee + state weight tax + county weight tax (7.5¢/lb for trailers on Oahu) + $5 surcharge — a 3,000-lb trailer on Oahu runs about $329/yr (lighter rigs on neighbor islands far less). Because motorhome MSRPs are large, value-based charges hit RVs harder than any other vehicle class.

Frequently asked questions
How much does it cost to register a motorhome in Hawaii?
Motorhomes follow Hawaii's regular vehicle fee system (motorhomes use the same weight formula; coaches over 10,000 lbs cap the state weight tax at $300 flat but county rates still apply) — use the calculator above with your RV's MSRP and weight. In value-based states a $150,000 Class A can cost several thousand dollars a year at first.
Do travel trailers register differently than motorhomes in Hawaii?
Yes — travel trailers are towed, unpowered vehicles and run on their own schedule (about $329 per year), separate from both motorhomes and small utility trailers.
