you can usually add around 400lbs. for the normal "options" that aren't included in the "dry" weight. things like: oven, a/c, awning, battery, spare tire, microwave and so on.
mine weighed exactly 400lbs. over the "dry" weight, when it arrived from the factory. that was without battery, propane, water and cargo.
