MISS KITTY- There can be a lot of differances. Campers are designed to camp in so there are cabinets and storage everywhere. They are also made to be either pulled from place to place or they can sit. They are like RV's without the motor. You can get them tiny or HUGE. I have seen $100,000 campers with a huge living room,2 big screen tvs (one in the bedroom), full size shwer and tub, leather furniture, all the goodies. I have also seen teeny, tiny ones that I could only imagine being used to cook/bathroom in and keep stuff cold in the fridge. I think I would suffocate trying to sleep 1 person in there. It just depends on what you want and how much money you have.
Thanks for the book idea. That thing with the toilet was pretty gross/funny.
