Have done enough short holidays to test survival on solar power only (no other charging devices), and bit the bullet and spent a week in the Flinders.
Tuesday 27/9 arrived at Parachilna gorge (late p.m.) very pleasant, 25c with a 10kt breeze. 01.30 - 02.30 wed a.m. hanging on for dear life as wind gusts were 30+kts. Slept till 03.30 a.m. woken by thunder storm followed by more strong winds.
Wed. Beautiful until 15.00 when wind picked up again. Night time was as bad as the previous night. Hardly any sleep. Told wife weré outa here in the morning but after listening to the 6 am news the front had passed and was moderating, and the strong winds were all over S.A. and into Vic. so decided to stay. Much more pleasant.
The wind gusts were so violent, my main concern was the Cubs framing being bent with no way of straightening it which would make it difficult to close, and while laying awake in bed, I was timing the gusts at about every 30 seconds. If this continued in the morning, I would get 30 seconds to close the camper which would not have been enough.
Anyhow, the solar panels worked a treat and the CT can stand 30kt winds, so will be more confident next time.
