The best path for you may depend on how much time, money, and patience you have and your skill level. What level of finished product you are looking for may also affect what you do. How much do you love your little Burro
Give me an idea of where you stand on the questions above and I can try to help get you going. I'm about 90% complete with a frame off restoration of my Burro
, so I have been through the process.
BTW... I would not advise towing this camper as it is. The weakest part of the frame is the bend at the tongue. The frame is already thin metal tubing. It looks like you have significant rust and damage at this point. I'd bet your floor is shot also. A solid floor keeps the frame stiff and prevents frame flexing. A weak floor will allow frame flexing and metal fatigue. These campers are prone to frame failures. I think the two reasons above are the primary root causes. Don't want you or anyone else to get hurt.
