Windows

There are four Dometic Seitz S4 windows in the Camper made from polyplastic. They all have pull-up blockout blinds and pull-down flyscreens; these clip together (usually with great effort). The window blade hinges outwards from the top, held in position by one or two friction window stays.



Solutions

In off-road use along narrow tracks, the window surfaces rapidly get scratched. There are kits available to polish out these scratches, but it takes a lot of effort.

block-out blind kinking

Further, after much dusty travel the window blinds become harder and harder to raise and lower smoothly, tending to bunch up on one side or the other. The same thing happens if pillows or other objects rest against the windows.

  wooden strips stop kinking of blind.

The issue with pillows is obviated using two vertical wooden strips held in position on the inner window frame using Velcro.

The solution for dust ingress to the blinds' cassettes is not so simple. In fact dust may not be the sole issue and corrosion of the cassettes over time may be the more important factor. The multi-turn spring in the cassette and the tube into which it fits, both appear to have corroded and some dust has managed to find its way in too. The corrosion causes a lot of friction and sticktion between spring and tube. The spring must be removed and it and the tube washed out and lubricated using WD40. The spring must be retensioned: I believe the OEM springs were wound up 18 turns; upon reassembly I believe I wound the spring 22 turns.
