When you have a trailer that comfortably sleeps 4 and you are a family of 5, you have a tough decision to make. Either you give away one of the kids or buy a new trailer. Neither was an option, so we all agreed to modify the trailer we had. All three kids were involved right from the get go. We wouldn't have it any other way. What better way to have them appreciate their tiny living space than to have them build it!
