After a trip to the CAT Scale, Toyota Tundra owner Phil Walworth discovered that his Grand Design Imagine 2800BH trailer had an actual tongue weight of about 1,200 pounds, double the manufacturer's claimed dry tongue weight of 604 pounds. The total vehicle weight of his Tundra exceeded its GVWR by approximately 400 pounds.
RV manufacturers often list dry weights that exclude cargo, passengers, and water, which can mislead buyers. To gain more payload capacity, Walworth replaced his Tundra with a GMC Sierra 3500HD AT4 Diesel.
