Dengle, you're right about the weight stuff.
I moved all my tools, tent, chairs, and ladder to the SUV to get the tongue weight down to 500. About the only things left in my storage area are the plastic levelling blocks, the jack crank, and the coax cable for my cell antenna. Nothing under the bed except a couple pair of hiking boots. The weight is in the water, batteries, propane, and 8 inch mattress.
Re the generator, if your Sherline tells you you're getting heavier than you want to be on the tongue, maybe sell the Westinghouse genny on CL and get a dual fuel or convertible one that won't stink up your SUV. It would be a shame to have to give up on boondocking or camping in undeveloped state and federal campgrounds. Just a thought.....
