First time would have been around 5 hrs (initial set up on a myswag weekend @ Eildon back in Feb) this was mainly due to everyone coming up and introducing themselves and we stopped and chatted, received a lot of advice on that particular afternoon around different little things. As it was the first time we had actually set up, took all the poles and all the canvas pieces and kept on picking up and putting down every pole at least 3 times as we had not done the annex roof before.
Last time out took 2 hrs, as all the poles that are not needed and extra canvas room are now sitting in the garage as well as all the tips we received from our original outing are now well and truly ingrained in memory
