I would look for a used trailer from a dealer, not a private sale. Look for features that you need. We need night stands to put our "stuff" on. Some brands do not have night stands and that makes it harder to make the bed. You have to reach too far past the wardrobe to reach the top end of the bed.
Stand in the shower. Can you stand up in it? Does it have enough elbow room for you? Do you have to walk through the kitchen to get to and from the bathroom? Is there enough storage in the bathroom? Today most bathrooms have one towel ring and very little storage below the sink. Trailer mattresses stink so plan on getting a good "Camper Queen" mattress. You always get what you pay for in used trailers. Cheap is indeed cheaply built and designed.
