a recreational trailer has a central longitudinal bathroom at one end , with a refrigerator abutting a bathroom crosswall in the fixed central portion , and a kitchen counter at the other end of the fixed central portion . the bathroom has at least one door in one longitudinal wall , usually two opposed doors in its longitudinal walls . two slideout rooms provide space when expanded for two bedrooms adjacent the bathroom . doors attached to the longitudinal bathroom walls when closed meet slideout stub wall panels from the slideout room outer longitudinal walls providing bedroom privacy . when two bathroom doors are present , both are lockable to provide access to and privacy in the bathroom , which has shower , toilet and vanity . the slideout rooms extend along the bulk of the trailer and provide space for kitchen and dining room . the advantages are that the weight of bathroom , plumbing and tanks is along the central axis as is the weight of much of the kitchen , which makes road handling easier than when the weight is on one side and off center . the extra width also shortens trailer length reducing cost of material . the trailer can be towed or fifth wheel .
