I'm currently looking at a horse trailer with 4 horse stalls and a living quarters. The short wall (because they load the horses in at an angle) is 13' long and the width between the trailer wheel wells is about 75". I've got full width axles so, once I've removed the horse related stuff from the "garage", I may have to get creative to get my hubs past the wheel wells. The trailer weighs around 10,500 lbs and has a 17,000 lb gross weight so load capacity shouldn't be a problem. Plus, horse trailers are built on heavy duty flatbed trailer chassis because they have to be more robust to go where the horse people like to go to ride their steeds. Only problem is I'm going to have to do some significant surgery to remove the stalls and mangers.
