No Slide Out Travel Trailer

IMHO, travel trailers are not intended to be permanant domiciles - espically in winter. Living in GA, will give you some slack, but you will still need to have heat in the winter - it was 17 degrees in Atlanta yesterday. People in your position often make fatal mistakes when using alternate methods to keep warm. TT walls are arounf 2 inches thick and not well insulated. Your choice of a non slide out unit is puzzling - have you ever been inside something like what your looking for? As you state, you will also be using this as a place to work with lots of supplies piled up plus a service dog. I urge you to reconsider.
