our 2011 13' SCAMP
a few months ago, got over 21 responses, set up one hour appointments with "first come, first served". We ended up selling to #3 on our list which was a lovely family with young children.
Our 10 years of camping with the SCAMP
experience, and many years of car camping and back packing, taught us that it's very easy to camp without a shower nor a toilet. A porta pottie is enough for nighttime pottie trips and practically all campgrounds have showers while ALL have toilets (if only pit toilets). Unless you are going off-road on private or BLM land you will not need a pottie nor shower. Honestly, if you are truly camping you can sponge shower. That said, people approach camping, even with a trailer, in varying ways from "roughing it" to "glamping".
