Not to mention those 36 lb Scopema Swivels - (two in my case plus another 5 lb for flat bar aluminum spacers).
I know... I need to have a build thread and a link... but this is an aluminum build - in fact, using hollow-core 30mm extrusions instead of solid-core and/or 1.5-inch. But each little luxury adds weight. The four 200w panels on the roof aren't all that heavy; but the way we mounted them - with the intent to tilt - added dozens of pounds. And the raise/lower bed added nearly a hundred pounds. Each little luxury: water heater, water storage, oven, slide-out tray, etc. If you look at the interior, it looks downright Spartan.
