RV Cost Calc

RV Cost Calc methodology

We separate public benchmarks, estimate assumptions, and user inputs so every calculator produces a planning range instead of pretending to be a repair quote or certified weight ticket.

Capacity calculators

Tank calculators divide usable tank capacity by per-person daily consumption for the selected travel style, then surface the limiting system first.

Repair calculators combine material benchmarks with labor-hour ranges and a user-selected DIY, mobile tech, or dealer labor rate.

Tongue-weight calculations multiply gallons by 8.329 lb/gal and distribute that load by the tank's distance between axle and coupler.

Repair calculators

All source rows include sourceUrl, source type, and as-of date; estimates are explicitly marked when no public rate card exists.

The tool reports ranges because RV brands, access panels, roof condition, and shop minimums can change the final invoice.
