What truck do I need?
1-ton truck recommended
Start with a properly equipped F-350 or 3500; payload may require dual rear wheels.
- Maximum loaded RV weight (GVWR)
- 13,000 lb
- 13,000 lb (exact-unit certification label)
- Tow rating to plan for at full GVWR
- At least 13,000 lb
- Conventional / bumper pull
Allow for 1,300 lb–1,950 lb of tongue load at full GVWR. Planning estimate only (10–15%), not a measured weight. Add passengers, hitch hardware and truck cargo when checking payload.
Check your exact vehicle before towing
Unloaded reference: 9,302 lb (exact-unit certification label; not a current scale ticket). Loaded weight will be higher.
Truck classes are shopping recommendations, not manufacturer minimums or towing approval. Check the exact year, engine, axle ratio, cab, drivetrain and towing package. Loaded truck and trailer weights must stay within towing, payload, GVWR, GCWR, axle, tire and hitch limits. Use scale weights to confirm the combination.
Exact-unit labels take precedence over model references. Never use dry weight alone to choose a tow vehicle.
