What awning

[Oldman]

OK, seems we've lost that Thread.....
(I might move this to the Camping Section for folks to put up what they have/use.....)
Meanwhile, this is a pic of mine setup, without any extensions....Note: The poles were shortened to pitch the awning as we had (predicted) heavy rain the night before.
(I have additions that double the length, a sidewall that can be used to increase the width and recently added a separate rear awning, roof bar mounted....)

   

If you zoom in, you can see the additional, cranked member that clips in-between the sloping arms to provide additional support to the sail.....works a treat.
It also provides something for my magnetic LED camp lights to be mounted on.....

The mod. I did to the flip out arms was to use marine fittings to allow the arms to slope downwards without placing stress on the pop top. As you can see here, the arms are really made to swing out at 90 degrees....something that can't be achieved when the awning is mounted on a pop top and the pop top up.....

   

This is what I did to alleviate the issue

   

Now, the pop top has no stress on it whatsoever from the arms/poles when everything is setup.

   

I would also add that the additional weight of an awning mounted to the pop top will cause the pop top to sag a little....the scissor strut springs are not strong enough to support the additional weight.
There are a number of work arounds, from vertical legs/posts added to take the load, drilled channels and a bolt dropped in to prevent the roller moving backward under load etc.
I chose to swage up some s/s cable and fittings that I can clip in and tension up, to keep the scissor struts supported.
