The Starcamp is a Dorema brand so if you need any specific accessories such as the storm straps for extra security in windy conditions then you could buy them online.
I've had a couple of these, they're good, well made awnings.
I've never used one on a seasonal pitch but I can't see any problem using one like that. Depending on size etc, a few extra ridge poles wouldn't go amiss to stop water pooling on the roof and make sure it's well nailed down before leaving it, especially if you're in an exposed location.
Just noticed you've got a 540 challenger as well. That was what we had as our first van, loved it and it got us hooked on the whole caravanning thing.
Good luck.
Had a Starcamp and found it excellent value for money.
Dorema quality at budget price. As per above post all Dorema accessories fit so no spares issues.
