Bailey Orion - What are they like?

Hi everyone. We are wanting to change our van to an Orion 530/6 and were just wondering how other Orion owners rate their vans.....build quality (never owned a Bailey), any niggles you have had, lack of outside storage, gas locker (access to) and one thing that struck me is the main door opening out towards the front of the van and using a porch awning with it....i.e. doesn't appear to be an awful lot of awning rail left to use when the door is open...all advice gratefully received before we sign on the dotted line! Roger.
