Sounds like you want the "UVW" unloaded vehicle weight. Its usually not included in the published specs. But can usually be found on a Mfg weight sheet somewhere on the actual unit, inside a cabinet door, on the wall panel next to the drivers seat or an external plate. UVW is supposed to include the operating fluids like fuel, coolant & oil; but not any RV tank fluids like water, waste, propane. Those are part of your cargo carrying capacity.
Note that the UVW is not an actual weight, but a calculated weight based on a typical unit; and usually excludes any optional equipment. So you always need to confirm it with an actual scale weighing to confirm you don't exceed GVWR or either axle rating.

Where can the curb weight (full fluids) be found for coaches? All I see listed is the GVWR but they never mention the starting weight of the vehicle before the owner gets in and brings gear.
