I MUST add the 8ft bag awning we have is not the easiest to open and close. can do it myself, but having a second pair of hands is always nicer anyway. If "mobility/agility" is an issue, I would REALLY recommend something more user friendly, like a crank model!
Also IF you have to retro fit a channel for ANY awning you will most likely end up with a series of expossed rivet heads on the inside of your trailer. This is NOT going to be a concern for me, as this spring, when I repaint the inside of our Trillium
, I'll coat the heads with a shot of paintable white silicone before I paint
Care must be taken will any awning not to let it get airborn in any windy situations. Our awning lifted up and overtop the trailer at a meet last spring, maring our new paintjob. NOta big concern, just some more touch up work to keep the trailer looking as best as we can
