Looking for small, lightweight trailer with dry bath

Thanks. I will explain again...we aren't looking for beds for everyone. I'm not looking for something we can all hang out in. As I said, we won't be spending much time in there. I would continue to tent camp but it's getting harder for me to sleep on a cot and we need a bathroom.

Edit: Although I do like that model you mentioned! I wonder if the weight limit is better than a bunkhouse would be?
