The problem is the awning material has to be attached to the side of the trailer so that the support frame will work and not leak down the front of the trailer.
My whole awning will slide out of its holder in just a couple of minutes work by just removing one stopper screw and slide it out of the groove.

The awning material has to be secured to the side of the trailer roof to hold the support metal rails tight when you slip them into the two trailer points when setting up. To rig up something else to use would be alot of work as it has to mate up with the mechanical part of the awning hardware that awning is sewed too. I was thinking of removing the mounting hardware and come up with a slot to sit the two rails into then I can attach the mechanical structure that holds up the awning material. The only part of the awning I would use would be the mechanical metal support items and down poles.
Then throw a 20-30 foot tarp over the whole trailer tie off to the ground on the back side of the trailer and let the front side extent out over the slipped in awning section metal support. Then tie off to the ground with ratchet web straps. I have done this with my present extended awning and only takes about five minutes but without the parts in the awning I need to come up with another mount idea to the edge of the patio side roof.
Never took any pictures of it but you can get a pretty good idea from this google photo showing the awning extened out front. I had two holes in my 20-30 foot tarp to allow the roof mounted air conditioner to go through it as well as the fantastic fan being opened up.



This is my trailer and the 20-foot side of the tarp fits over both bed ends and the 30-foot side would go over the whole trailer with the Air conditioner and roof mounted fan poking up thru the slot holes. The two awning poles can be used on my setup as shown here or go straight down the grounds. The back side of the tarp would angle down to the ground and tie off to ground anchors. This makes for a nice place to stack firewood.. The front side goes out over the existing extended awning and then you stake it off even with the edge of the awning to the ground using tent poles and ground anchors with 1/2-inch ratchet web straps. The web straps will let you remove this is a couple of minutes if high wind comes up real quick. Certainly gives you a full cover for sitting under for the whole length of the patio side of the trailer from one tent bed end to the other.
All of the to save purchase of another $600 awning haha...
