Our older Trillium
came with an oversized rubbery awning
that is a couple of feet longer than the track. It sagged quite badly and gathered rain! I wondered if a ridge pole (like those on old canvas tents) might help. Hubby put on his thinking cap and came up with the one in the photos. The pole beside the camper fell down when the wind came up and hubby created a quick fix with some rope he had in his 'Might Come In Handy Sometime" box.
You can see that we also put Velcro around the awning
'frill' so we can attach the walls for our canopy as windbreaks or shade makers (depending on the weather). This we have found to improve our comfort level quite a bit.
Now I'm wondering what we could do so attaching the canopy bug screens will actually keep the bugs off - they come from under the camper! Maybe some Velcro along the camper with the bug screen zipper in front of the door?
