I'm not too worried about the components and wiring installed thus far. The components are all known-good name brands (Victron, SOK), and having been deep into the guts of the factory wiring on a couple RVs, I know my work is for damn sure better quality and/or heavier-duty than what most RV manufacturers put in. I also know there's little to no chance that I'm going to pull any of it out, considering what a monumental PITA the installation was.
But beyond this point... some of the changes I'm thinking about would be, oh, let's say, more tech geek oriented than something an 'average' RV'er would be interested in dealing with. That stuff would *probably* be easier to pull out down the road, though that would be some what sad to have to do.
