Our front shade on our 2020 Canyon Star stopped working, suspected to be a bad motor.
In order to use it, we slid the guide out of the slot, on each side, then the wife & I rolled it up until out of the way. At that point , I used , 2 bungie cords which were long enough to go around the partially rolled up shade. These hold it in place fine, & when we need the privacy, we undo the "bungies", & roll it down.
No need to ruin the headliner, upholstery, nor anything else from "duct type" residue! This is a simple fix, & works well, until you can get the shade motor replaced.
That's what we have done, & Newmar will fix it when we go to Napanee, the first week of August!
Life is filled with bumps in the road, especially the "RV Life"! Though frustrating, accept & enjoy the challenge! Life is too short to get too terribly upset!
