Trailer construction

摘要

A desirable travel trailer can be constructed so that the internal floor within such a trailer is capped by a series of joists located on the chassis of the trailer. The spaces between the joists can be used to hold various tanks and other items assocated with the use of the trailer. Preferably the tanks which are expected to be heaviest as the trailer is used are located directly above the undercarriage of the trailer so that the tongue weight of the trailer is not altered or significantly altered as the weight of such tanks are changed due to changes in their contents.
