We've just been away to Carsington Water for the weekend and instead of taking the full awning thought we'd try the Omnistor Safari room which we had on our Familia. I was not sure weather it would fit as it is only 2.6m long and we also have a higher railed Troll so it was more of an experiment for weekend use.
It seemed to fit well as far forward as it could go and just missed the rear side window and locker.
The van was on a levelling ramp on the awning side so should be better next time but it still pegged down well and worked perfectly. I can erect it single handed in around 10 minutes.
