We wanted to leave for a short trip and rain was predicted. Since I hadn't taken much of a look what was available in the way of ready made awnings I decided to just temporairly go with a tarp.
Then I thought, "why not just make up a couple of poles to hold the outer ends". Then I thought, "why not make a couple of cross poles also" Then I thought, "hmm, what would happen if the pole on the trailer was pulled back tight into the ridge in the roof" and before you know it I'd made an awning
I only used a white poly tarp thinking it would only be temporary but it worked so well I won't be in any hurry to change it.
We used the
awning in heavy rain and it worked well. The ropes hold the pole on the roof both down and pulled sideways firmly against the ridge. There is a pole running to the outer pole at the center point. It serves to keep tension on the tarp and provide a mini ridge causing the water not to be able to pool in the center but to run and drain to either side. There is also an outer flap that drops down, if required, to block evening sun.
This might be an "accidental awning" but it works for me.
