If you are to buy brand new, I highly recommend 16th footer although Scamp and Casita do have 13' trailers with bathrooms. They are options on the 13' Scamps although if you want as standard, Casita do have 13' with bathrooms as standards.
Scamp, Casita, Escape, Trillium, Trillium Outback (Canada), Lil Snoozy, ParkLiner and EggCamper are still in business. The rest you find on the other website are out of business however, they DO have parts because most of them are similar built and has similar supplier parts such as Dometic Refers, etc.
If you are buying used, you can buy any and repair it yourself. Most of them are self-repaired. Also you can do is to buy a used one and remodelled to add bathroom. I recommend 16' or longer to do that one.
You can buy direct from owners, no dealers. They usually do not have dealership.
You can also order yours and it takes about a month before you can get yours at the factory. You can either pick it up there or have it shipped.
