No real input here on the project at hand, seems the OP has things well in control but I get a kick out of reading about managing the minutia of the detailed tasks all in the interest of preserving the original configuration, where there is likely little reason and some risk to preserve it in the first place. After a few decades of building and fixing stuff from cars to motorcycles to electronics to houses, doing the "surgical" repair where one tries to disturb as little as possible and retain as much of the original integrity is wishful thinking bordering on folly. For a long time now I view every project as scorched earth, wipe it clean and start from scratch. Saves a lot of piddling around trying to get things out intact, having to clean stuff up and often only to find you end up starting from scratch anyway because some hidden damage is discovered or OEM parts can't be sourced. If one was restoring a priceless antique then the painstaking process is warranted. An RV that gets used, sits in the weather and has birds poop on it will suffer zero intrinsic value impact if one were to install something other than an OEM part or in a different way. My goal is to make it work, and make it better than I found it which with RV's is usually not hard to do. Tear it all out, salvage nothing, clean it bare and bring it up from there because more often than not you're time and money ahead.
