Question about dry weight and actual dry weight

yellow sticker weight doesn't include battery weight and propane weight, since those are done by the dealer.
only a motorhome will have the battery weight included.

it's very common for the actual yellow sticker factory weight, to be 300-400lbs. more, since the fictional brochure/website "dry" weights don't include the weights of: awning, oven, microwave, a/c, spare tire, water filter and so on. brochure "dry" weights are almost always for a stripped-down basic trailer.
