A housing and trailer system comprising a trailer and a housing. The housing includes a lower housing and an upper housing and may be positioned on friction-reducing members that reduce friction between the housing and trailer. The reduction of friction facilitates the housing to slide more efficiently on the trailer. A safety lever and linkage system operates to safely move roof support structures and raise/lower the upper housing. An adjustable cargo system is attached to a roof on the housing. The adjustable cargo system is adjustable to receive and/or secure different sizes of cargo.
