We have an Rv on site. It is 35' but doesn't have any slide outs. It works for two people, my wife & me, but it does get too close for comfort sometimes. If I had to do it over, I would get one with slide outs next time. We have a generator, water tank cistern, a water pump & pressure tank. This set up gives constant pressure water like you'd have in an RV park as long as there is water in the tank and the generator is running. The RV does have an onboard water tank that can be filled from the water cistern.. The onboard water pump is 12V so you can have running water in the RV, which runs off its batteries, without the generator running. Next step is to get a septic tank set up. No code restrictions out here but we want to do it right so we don't have a mess on our hands down the road. Might like to experiment with a composting toilet ystem to cut down on water use. I think an Rv cover is in the near future too. Shade makes a huge difference. Did I mention it gets hot out here?
