1963 model Air Flow trailer

Lavender I think you have to answer a few questions before you get the proper advice you are looking for.
1 Do you want the trailer completely restored for your personal use or to sell?
2 Do you have the place and time to completely rebuild this trailer?
3 Do you have the tools, talent, and desire to take on a project of this type?
4 Are you physically able do the work?
5 Do you have the money to spend (it can run into thousands of dollars)
If you have answered yes to the above questions then you have to decide if you are willing to spend a year or so to do it. If you are doing this to attempt to make money you most likely will have more in it if done properly than you can sell it for, but if you are doing it for your personal use then you will experience a great satisfaction taking it camping and being able to say "Look what I did' I started with junk and turned it into a show piece". The rebuilding of a trailer is a long hard project that requires a lot of effort to stick with it to the finish, especially when things go wrong and you have to tear out a section that you have worked on for days, then go buy more materials and start over.
But like I said above if you are doing it because you love the old trailer and you want to keep it and display it and your effort then it will be time and money well invested.
This is just my opinion and it didn't cost you a cent, but give it some thought and try to answer the questions honestly then you will have your answer.
WELCOME TO VTT

Thank you Bill,  I love the floor plan in this trailer,especially where the benches and the table are.  I will go out to my trailer and sit and have coffee or Iced tea in the early part of the day and enjoy the view of my garden. There are big windows in the eating area.  I don't want to sell this trailer,really.  And I don't want to make any money off the sell of it.  My dream is to have a few trailers to go camping with my family.  I like how you brought out the fact that I may have to tear apart work I may have done on the trailer. I don't give up easily.  I am a seamstress and I know about tearing things apart and redoing the work.  I know sewing is not a real physical job but it is a mental job.  I am hoping that taking  and putting a trailer back together may be like putting pieces of fabric together to make a garment. I have read many blogs stating that it would take a year to a year and a half.  And if I don't succeed, at least I can say I tried.  Thanks

Welcome Lavender.

You can do anything you want to do. Having a seamstress background will allow "thinking out of the box" and compromising. LOL.

We're here for you. Pictures are requested.

One of my teardrop buddies came to look at the trailer and felt it needed too much for them to tackle, they really didn't have a place to work on it. I called about the trailer but didn't get a reply. It is on CL for $1500, possibly it was listed too high with the work it needs, but I am no expert. I already bought another camper but I thought this one was very cute.

Hi,Soup, what are cheater blacks and what are ceiling supports and where do I put them at, when working in the back? Thanks you

Lavender,
Congrats on deciding to fix up your wonderful little trailer. In some ways, doing this is a lot LESS frustrating than sewing. The pieces are bigger for one thing, and you don't have to pull 572 tiny stitches on that gathered bodice on your granddaughter's christening gown. On the other hand, few people have had to head to the Emergency Room to treat an injury incurred while doing a felled seam.

Cheri is right, keep a fun project on the side. When you have pieces and parts everywhere, it's late, you're tired, and you just mucked up another layer of polyurethane on the drawer fronts, it's nice to take some time to think about how you're going to do your curtains, or to pick out just the right dishes.

As far as the J-rail, you can certainly straighten it yourself, you could have someone else do it, but if you get it good and warm (hair dryer will work) to soften it up a little, it's really not that hard. Or yours could be like ours... in such bad shape, that the only thing to do was to dump it and start over with new stuff.

Good luck!
