Last year we had the wind get under one of the crank out windows in our fifth wheel while driving down the road. Had to use 100MPH tape(duct tape) to get it home. It ripped the mechanism up so we could not just replace that. I decided to order a new double pane slider type window for it from Buckaneer RV Supply. We had another trip coming up and needed the window in short order. The people at Buckaneer assured us it would arrive at least a day before we were to leave. It got there a couple of days sooner.
The replacement was pretty easy, it does help to have two people. As for the installation, remove all the screws and take out old window. Clean up the old sealant and caulking. Add new sealant to the window, put in place and slowly tighten the screws, kind of like on a tire, opposite sides all the way around the window. It will take several rounds to get everything tight without warping anything. Then just caulk around it.
