Know your numbers before you tow.
Payload, loaded trailer weight, CAT Scale math, weight distribution, tires, power and trip cost — organized around the questions tow vehicle and RV owners actually need to answer.
What do you need to figure out?
Choose a question first. Your RV weight and truck-specific ratings determine how reliable the answer can be.
Can my truck tow this RV?
Compare the whole setup. Verify your exact truck ratings and identify unknowns before relying on a result.
How much can my truck carry?
Account for people, gear, hitch equipment and trailer tongue or pin weight. Unknown loads are not zero.
How heavy is my fifth-wheel pin?
Estimate pin weight for planning and check payload; confirm actual pin, hitch and rear-axle loads.
