I called the manufacturer of my soon to be delivered fifth wheel and was surprised to find out they keep a weight record of every trailer as-built. My dry axle brochure weight is 8853 vs 8930 actual. Dry pin brochure weight is 2023 vs 2320 actual. Does not include, of course, batteries and propane fuel. The difference is mostly due to the 5.5K generator. I will weigh everything when I get it. Last time I weighed my TV with three adults and 1/2 tank of fuel, it weighed 3400 steer and 4600 drive (scale readout is in 50# increments).
