Dan your camper looks to be in excellent original condition for the most part. Amazing find, no water damage apparent like in the front cab-over v-wall. Very nice. I like your poster above the sink. I'll have to send you more files. I have that picture in an original sales brochure on pdf.
It's too bad the photos all went away (that whole photobucket thing back ago) because the write-up loses a lot without them. I have pdf files on the entire project with pictures I could send you. I think it was in Chapter 3 - Structure, where I described in detail how I beefed up my corners.
In the meantime it looks like you are doing under wing mounts, which may be add-ons or may be originals. I'm sure you'll get it how it needs to be.
Yes, I still have a set of Safe-T-jacks laying out in the field. I used them once - when we picked up our first (10.5') Travel Queen in the pasture as described. Lil Queeny is our second and an 8'. Those under wing mounted grids have pipes in them to receive the flip-up Safe-T-jacks. The pipe placements in the grids actually set the four jacks for that camper's center of gravity. My 10.5 is in the landfill. It's not easy to take out a grid - they are quite integral to the box and wing framing.
Let me know if you want need the entire series with the original pictures. Many chapters were one pdf file, but several of the chapters generated GOBS of pdf files for just the one lengthy chapter. I used this site's print feature. It was a lengthy process, but I got them before Photobucket fully flushed.
Good luck!
