Cop out on DRV's part, if you ask me, and they're =far= from alone on this. I'm no coder, but =I= can easily logic out a program that would give you estimated weights on a "build your own" basis. The "brute force and ignorance" method would be to simply take a sample of each model and weigh the damn thing at several stages of construction so they know that it weighs X, but weighs Y when you add a larger fridge, weighs Z when you add washer/dryer and a xxxx watt generator adds another ABC lbs, etc., etc. Could even hoist the pin on a forklift with a scale at each stage to see how =that= changes, too. Again, the engineers have all these numbers in their databases and they know what the moment arms are fore and aft and left and right, so it really shouldn't be hard for a coder to come up with a program to calc all this and put the results into a template to show us. Any bets on whether any of the total-custom RV builders do this on a total custom build?
