What can a Toyota Tundra (i-Force Max, tow pkg) ('22-26) actually tow?

The rating is the easy half of the answer. A trailer never weighs its brochure dry weight — water is 8.34 lb a gallon, propane and batteries ride along, and so does your gear — and hundreds of models changed their published weights mid-run, so the model year decides as much as the model. Judged that way, with a 10% margin and 2 people aboard: 3609 of 5150 campers fit a Toyota Tundra (i-Force Max, tow pkg), and 10 more fit if you buy the right years.

The number that quietly binds is payload — 1,940 lb (SR5 Double Cab 4x2, 6.5-ft standard bed, i-FORCE 3.4L twin-turbo V6 — the single configuration Toyota rates at 12,000 lb. Every other Tundra is 1,200-1,885 lb.): tongue weight lands on the rear axle with your passengers and the hitch, so a vehicle often runs out of payload well before it runs out of rating.
