Slowmover, the weights I reported earlier were computed from scale readings: combo minus truck. At that time the Tacoma was the tug, and all axles had margin to spare. That was fully provisioned "wet" weight. I don't take all my cast iron cookware on the road but it was loaded with food, water, clothes, dishes, etc.
I did correct my numbers to include the generator as show in that pic. The tongue weight was 550# without the generator. I have not scaled the Tundra yet, and the motorcycle adds another variable that most folks probably would never encounter. Different trucks have different base weight and margins so trailer numbers alone seem better focus for this discussion. Everyone needs to do their own homework anyway.
The battery bank is 200-Ah which can support the Danfoss compressor fridge for several days. No solar panels yet but eventually. Meanwhile, the generator keeps the batteries topped when anchored.
The 20-gal fresh tank might last a week if we're frugal. I modified the shower head for example. I stow a pair of 6-gal jugs to schlep water to the trailer if needed. The twin 20# LP tanks are BBQ exchangees to which I am not particularly attached. So I don't have to tow the RV to a qualified station. The broader theme is strategy for flexibility and options. The bike can mule a surprising amount and type of provisions (gas, LP, water, food, whatever) and at 90+ mpg it's awesome for errands.
The trailer axle is torsion. The internal rubber is self damping. Folks argue about whether they should be stored weight off or not. The jury is still out on that. Some folks have 30+ year old axles that maybe sag but seem to work fine. On this 1988 resto project I'm selling (
Scamp 5th Wheel) I converted it to leaf springs so the trailer can be easily matched to a range of different pickup bed heights. (The old Dexter TorFlex went on CraigsList quickly with takers racing each other to get it - still good.)
Thanks for the kind words about my remodeling work. It's fun during and rewarding long after. These projects often provide a great excuse to learn a skill, or get tools.
Cheers
