We all have different ways of looking at things. Building on your wish to keep the existing units, Gordon's input of repurposing other AC units, and my positive experience with the Dometic's ability to freeze you out without the usual AC noise, I think you may have to investigate the possibilities.
You said "Of all the tools I own for HVAC, I do not have a recovery machine, tank or the capability to sweat silver solder. Perhaps If I did, maybe I could go a little further? (Recovery of R22 and disconnection of lines)"
A recovery machine, a MAPP gas turbo torch, the recovery tank, a set of scales, and a tank of Nitrogen will set you back less than a thousand dollars. You have already experienced that is difficult to get anyone to look at the unit. Don't bother with an RV tech. You may want to think about equipping yourself to keep those units going. I am with John Kosir, if it breaking into the system is not 100% necessary, then don't. On the other hand, having the ability to work on them frees up a ton of options.
Part of the fun challenge is putting the noodle to work to keep those old girls up and running. You have already demonstrated your dedication to doing that, and you have also demonstrated that you have the technical skills to learn what you don't know about
AC systems. If a mule like me can learn it, then someone like you will ace it.
