Here's my two cents worth, for what it's worth...should be worth two cents but may be less. I may be mistaken but I would think most ofus gals have already put eight thousand miles on our rigs and all the bells and whistles are still working with no knobs or screens missing from anything. I am a little curious about the stains in the sink that does mean the entire water system likely has those stains too and ya gotta wonder "What the Heck did they do to make those stains". All of us have been through many different states where water is different from place-to-place but we haven't created or even allowed stains like that. A 2010 should have stain resistant types of sink material so that is quite curious to me. Geez, were they mixing up crack in there?
Also, I would be interested in what the other gals have to say about central vac's. All the women (without fail) that I have met in my travels who have central vac systems are gravely disappointed in their lack of suction and don't even use them anymore and have bought their own traditional vacs. Not that it's a big deal to have one in any rig you decide on I just venture a guess that you likely would be fine if the rig doesn't have central vac.
Gosh, forgive me for maybe being too dogmatic but I would keep looking to find a rig that is near "cream puff" condition before spending money on an inspection.A 2010 should be near pristine, if not totally pristine. These owners sound as though they were darn tough on things and you can find better.
I sure do agree with the Rear Living configuration, it is so much larger for your tall husband and gives a lovely sense of "small apartment" living and the large viewing window in back is just a lovely thing to have.
