Back in the '70-80s, there was apparently something magic about 1,000 lbs, so a lot of the small eggs have dry weights just under that, most of which turn out to be somewhat fictional, esp if the egg had options like batteries, fridges, spare tires
, etc., so all the dry weight stickers and labels have to be viewed with a healthy dose of skepticism.
Actually, a more useful number is the GVWR from the trailer label, because this is the maximum the axle(s) should carry -- Multiply this by 110%, to account for tongue weight and that's a more real-world weight to deal with for early planning purposes.
But once one actually has the egg, one should pack it all up with personal effects, liquids, food, tools, etc. and take it to a scale and weigh it -- This is the only weight we really care about because this is what's going to need to be pulled, steered and stopped -- All the rest is theory and guesswork! Then one can go about setting up proper tongue weights, side-to-side weight distribution, etc.
Same for the tow vehicle, BTW. Once one adds in the driver, passengers, luggage, tools, receiver hitch, etc., it should also be weighed.
