12 in brakes. Heater does run propane. Batteries will charge from truck.Awesome job!
You plan on running brakes on it? Does the On Demand heater run on propane?
That Blue Sea Electric bus is great. I just put one in my 60 for all my accessories.
Are you going to run power from the truck of the trailer have it's own battery/solar set up?
I'm probably not much help, but I know of two ways: (1) Electric actuators that raise the roof (4 of them). (2) Gas struts similar to what you showed. These are on the outside, but the ones I've seen (and 1 I own on my RTT) have them on the inside and wrapped in cloth to keep dust away. Here are two photos to help you think it throughOkay. I'm having builders block on how to accomplish the pop up roof.
You can make your own composite panels. They don't have to be FRP (fiberglass reinforced panels). I have a book called "Build your own overland camper" by Steve Wigglesworth where he talks about extruded polystyrene foam as insulation and 3mm marine ply outer skin. We have more high-tech materials now (the FRP), but it is expensive, and there's nothing wrong with this other approach, IMO, as long as it's structurally sound.I'm definitely using aluminum for the framing. I looked into composite panels, but they were either extremely expensive or unable to get here in SoCal. What are your thoughts? I'm open to suggestions.
