Our 3mtr deep awning is a proper all weather seasonal awning and as such is made from heavy duty materials. In standard format it comes with steel poles which are very heavy. The awning fills our thule atlantis 200 roof box, and I put the poles into a strong canvas bag and strap them to the roof rails alongside the roof box. I would estimate the weight on the roofrack to be 100kgs which is the max for our Rover. I am considering changing 4 of the roof braces to carbon fibre and leaving the 3 main roof poles as steel to save some weight. But I don't want to compomise the strength of the frame as, we had 7" of snow on it last year which probably amounted to about half a ton of snow loading. As and when I return to conventional touring, I will buy a light weight nylon awning as then we will be fair weather caravanning.
In january we had to pack up the awning with 3" of snow fall on it and that was blooming hard work and nearly defeated us. This time around, I
will be choosing the day based on weather and not by the saving of £12 a night
.
I think a full awning is a team effort to put up and in any case, why struggle on your own when your OH could be feeding the awning into the rail while you pull the beast round. Our awning has an eyelet at the leading edge so that you can thread a cord through to avoid stretching while standing on the steps to pull the awning round the rail.
My awning companion is a great help with tensioning, also I have a long handled paint roller frame that hooks through the clamp screw to lock the awning in place. With my arthritic shoulders, elbows and a bad back, I need all the help and gizmos I can get.
If you have those plastic clamps or twist lock poles. A piece of cycle inner tube and a jubilee pipe clip fitted to the sliding pole, will stop the poles slipping in high winds or heavy snow, causing your awning to droop.
