If you are handy with a sewing machine, or know someone who is, you can easily make your own rope + pull awning. That's what I did. I already had poles and guys for the uprights, and rope, so it was really cheap to make. Just needed to buy the tarp (Amazon). The C-channel was already on the trailer too.
You can also make it bigger than the stock awnings.
I made mine 10'x20'. Lots of room for a picnic table and a seating area with the lawn chairs. I have a 16'
Scamp.
The nice thing about it being longer than the trailer is that we can drop one or both of the ends to make sidewalls if needed (sideways rain, too much sun, close neighbours).
It really expands our living space and takes up little room to pack.
