As Speedy said .... Any Options add weight to catalog spec. the 3070 hitch weight is already listed at 2300 lbs. Generator, Washer/Dryer, dual pane windows, 2nd A/C, high gloss gel coat,.. these all add up to a bit of weight. Our 3055RL "Dry Weight" increased 750 lbs with 2nd A/C, Generator, Dual panes, Mor-Ryde, and Hi Gloss Exterior.... Didn't get it but Washer & Dryer would have been even more.... These options cut into your payload capacity for all your other stuff (clothes, kitchen ware, adult beverages)
