Personally, you might be looking too deeply into all this. I am replacing my slide motor in the spring for the first time. It just broke.
Many moving parts on these things and stuff will break, new or old.
I make a list of what needs fixing, and work down my list of the things I can do myself and so on. My list has always had 20 things on it since day one.. one goes off, two come on..10 go off, 1 comes on. Part of the hobby I guess.
We enjoy the lifestyle and the great places and people we meet as you will also.
Now get out there and buy one!
