Westend and Huntingdog have explained it well.The type of trailer the OP is talking about use a sandwich of Luan/foam/luan for not just the floor but the whole trailer, roof walls and floor. The box of the trailer is engineered to be part of the support structure as much as the frame. Some early models were failures such as Keystone Zeppelin that was replaced with Passport model.
