I am a do-it-yourselfer and I am interested in knowing about turning my single wide into a double wide mobile home by either constructing the other part or buying another single wide and putting the two of them together and the point is that I want the addition to be transportable for relocation. I want to know how to build the foundation so that it is transportable like the original side and how to connect the utilities together: water, electricity, air-conditioning, gas line, etc.
