How to size a trailer
What size trailer (GVWR) do I need?
Take your heaviest expected load, then size the trailer so its GVWR (gross vehicle weight rating) comfortably covers the cargo plus the trailer's own weight — roughly load × 1.35. A 2,990 lb GVWR single-axle suits light landscaping loads; 7,000–14,000 lb tandem axles cover equipment, dumps, and vehicles.
Single axle vs tandem axle — which do I need?
Single-axle trailers (up to ~3,500 lb GVWR) are lighter and easier to maneuver for small loads. Tandem (dual) axles carry more weight, tow more stably at highway speed, and are required above ~3,500 lb — choose tandem for equipment, dumps, and anything over about 2,000 lb of cargo.
How do I match a trailer to my tow vehicle?
Your tow vehicle's rated towing capacity must meet or exceed the fully loaded trailer weight (cargo + trailer). Also match the hitch class and, for heavier trailers, use trailer brakes and the correct ball/coupler size.
