Lantley, I agree that the dry weights are notoriously low. There is a 400 pound difference between my advertised dry weight and my unit's yellow sticker. Add to that, I scaled my camper when I emptied it for its trip back to the factory and found that it's 200 pounds higher than it's yellow sticker for an "unofficial" dry weight that is 600 pounds heavier than what is advertised. (See my "
Truth in Advertising post")
However, I was hoping that some truth would hold true between the dry percentage and actual wet percentages. In my case, they're close - my dry percentage and wet percentage are within 0.5% to 1.5% depending on how I'm loaded for a trip. No great surprises there when evaluating trucks or campers to trucks.
The problem comes when specific campers are 2% to 5% different in percentage points as I've now come to see real world/scaled examples.
So now I wonder if a "RV scaled weights database" would be a better utility/application for people researching units. The problem comes for new units where people haven't bought them nor had them scaled.
