ZR2nit,
The trailer has a solar panel set up, but waiting to decide on which roof rack people are going to want. Most likely something like what is on the trailer now. That allows the solar panel on top, or I could have Baja Rack make one that is higher. The trailer has a morningstar digital controller and plug in system already.
The shower is ran through the hot water heater and has an outdoor control.
Slide outs are nearly impossible with this design, due to the heigth of the counter, but you can use the fridge top as one and the cutting board covers the sink, giving you more room than the box trailers have by far. I am planning on moving the sink drain and going directly into a holding tank, that may give me some room, but I doubt much. It would have to be a cabinet affair I think, but the fridge would have to be in for it to be used. Still not a lot of room, looking at a swing out setup from the side of the trailer that might work.
Enclosures seem to be a problem, not having much luck around here finding someone to make them. Any one having contacts with a fabric man would be great. I had one, but he is not real interseted in doing them. He makes golf cart enclosures and is so busy it is sickening. Being close to Palm Springs and Hemet, the pass area, he never stops making them and has orders for next year already. Could be in the wrong business!!!!!
