RV Calculators & Towing Tools
Ten free tools for matching a tow vehicle, planning an RV trip and estimating an off-grid stay.
Updated 2026-08-12
Build the load first
Start with the towing-capacity calculator, then isolate payload and tongue weight if a limit is close. Use numbers from the exact vehicle labels and manuals rather than a model-wide brochure maximum.
Plan the drive
Check towing speeds and trailer brake requirements for every state on the route. Then budget towing MPG, campgrounds and other trip costs.
Plan the campsite
Water, waste, electricity and propane determine how long an off-grid stay can last. Use the focused tools to improve individual estimates, then compare them in the boondocking calculator.
Frequently asked questions
Which RV calculator should I use first?
Use the RV towing capacity and payload calculator first for a towable RV. It checks the four core vehicle and combination limits.
Are these tools free?
Yes. They run in the browser without an account.
Do the calculators replace weighing an RV?
No. They are planning tools. A loaded axle-by-axle scale measurement and the exact manufacturer ratings provide the final check.
