Note on edit: we do NOT have the duel pane windows, but::::::::::
You might have as well as non-lubricated windows, something I call slag.
Look in the tracks of the windows, in the area you will be moving the window to. See if there is a bit of black caulk in a "dot". They put it over the slag to keep the slag from cutting you (that is my take on it anyway). The worst we had was on the small bedroom windows, we could not get them up over 3 inches, should have gone up at least twice that.
They took the caulk off, sanded off the bump of slag, re-caulked, and BAM, the windows went up.
If you are still in warranty, you might consider a trip to the dealer for a checkup.
Welcome to the forum, congrats on fulltiming, go forth and enjoy!
