Good for the salesman swaying you away from something way too big. But, you need to become educated and not let the salesman tell you what you want to hear.
There are a couple of weights to keep in mind:
- Gross Vehicle Weight Rating (GVWR) - this is the maximum weight that the truck is rated to handle. This includes the weight of the truck, the driver, passenger(s), pet(s), all stuff in the cab, all stuff in the truck bed, the hitch itself *and* the amount of weight that the pin is pushing down on the truck (this is typically 20%-25% of the total loaded
weight of the camper).
-- Payload is the GVWR minus the weight of the loaded truck, passengers and stuff. Your truck is designed with a certain amount of payload, but as you add things to it, that is decreased. Though, I'll give Toyota credit for following the newest standards and includes a more realistic weight for driver + a passenger in their payload calculations.
- Gross Axle Weight Rating (GAWR) - this is the maximum weight that your axles are designed to carry. The front axle (FAWR) is designed to carry a different amount than the rear axle (RAWR). Again, this includes the weight of the truck pushing on that axle and a portion of everything in the truck.
- Tire Load Capacity - on the sidewall of the tire, it lists how much weight the tire is designed to carry. This carries the same weight as the rear axle.
- Gross Combined Weight Rating (GCWR) - this is the weight of the truck (all of the things in GVWR) and camper (including anything that you load into it) combined. You will a generally run out of payload before you hit GCWR.
Now, the next biggest question is to overload or to not overload. Personally, I'm in the camp that I feel the need to be within all of my camper's ratings. I don't know enough about trucks to be able to intelligently pick and choose which ratings that I'm going to believe vs. those that I feel like can be exceeded. For some, they knowingly exceed GVWR but not axle weights or tire load capacities.
Finally, I'm a strong proponent of taking a truck, loading it up like you were going camping and getting it weighed. Having the numbers in black and white let you make an educated decision. There are all sorts of scales all over the place - either CAT scales at truck stops near the highway, or quarries or dumps, etc. If you do weigh, make sure to get separate weights for the front/steer and rear/drive axles.
