I've mentioned this before: one issue with inside sunblockers is that they trap heat between themselves and the glass. 1) that's not as effective at keeping summer heat out of the coach as an outside cover, and 2) my experience is that the trapped heat accelerates the deterioration of anything caught between, from dash trim components to the glass itself over time.
William, I have looked and can't find my receipt for that job. I'm confounded because I am in the habit of keeping such things for eons. I've obviously put it somewhere I shouldn't have. You should research your own price anyway, as ours was made and installed at the Redmond FMCA rally 6 years ago, at a relative discount, and included entry door and driver's side window and wiper covers, as well as a couple side window awnings. A big rally is a good place to get just about anything like this done; often the professional labor is free. Though I don't recall the cost, I do remember jumping on a great deal, and after 6 years of use I can avow it was.
I thought leaving the cover on part of one winter in storage outside might have been a mistake, since previous covers had badly mildew stained. I finally removed this one after a few months of rain, following a summer of hot southern sun exposure, and did find black residue here and there, and was mad at myself for leaving the cover on. But I was subsequently amazed when the thing easily rinsed pristine clean, and to this day looks and fits like it did in 2007.
