I noticed earlier this spring that the door to RV was getting difficult to open. Didn't think too much about it at first (actually thought it was my grip getting worse, not problem with door). Last week it became impossible to open. I even went in thru drivers door and tried to push it open from the inside with no success. Two others tried and failed also. Finally a 3rd person was able to pry it open.
I see no signs of the weather stripping tearing/sticking to door and the lock seems to operate properly when the door is open.
Will it help (or at least not hurt the weather stripping) to spray it with a silicon spray? Or does anyone have a better solution?
