I don't remember the year but at a Rally in Shreiveport, The wind was continual. the tops of buildings you could see dust covering glass tops and then the wind would sweep it away. Very very Fine dust. Coach rocked considerably.
When we got ready to leave the awnings and room slide outs and the jack rebelled and it took forever for the jacks to come up grumbling and shrieking all the way.Couldn't see the dust but it was there. Noway for me to get under the coach spray down the rams with siiicone. When we got back to where we stored it. They cleaned it all up and told me about the fittings.I had them greased too.
maybe should have but they were there for the purpose I reasoned.
