Putting up a full size awning for the first time can be a little tricky, but after doing it a few times it becomes much easier.
Having a "trial run" either at a local campsite or in the garden if its accessible is a great idea.
For my first trial ( many moons ago now) I used magic markers to mark each pole with its position and an arrow for its directio, so to speak.
The magic markers soon wore off, but thankfully by this time I had got it more or less sorted out in my mind, however I did see in our local DIY shop 5 rolls of insulating tape (all in different colours) and at only £1 for all 5 rolls) so these replaced the magic markers.
I'm an old dog now (been a pensioner for quite a few years and not in the best of health anymore) but I can still put up our full size awning from start to finish in under an hour.
My secret was to ask Mrs paws to take the dog for a walk whilst I got on with putting it up, and to politely decline all offers of "help" from neighbouring caravanners:
that may sound counter intuitive but well meaning folks who try to help with an unfamiliar (to them) awning can actually confuse and delay the process considerably..... when the awning is up offer the well meaning help a cup of tea or a glass of wine so they are not offended by your politely expressed words indicating that you are OK etc...
Good luck with your first trip
Regards
