Had an Outdoor Revolution from Glossop Caravans, complete POS. The quality was appalling, nothing fitted & it leaked like a sieve. Took it back to Glossop, they said I was putting it up incorrectly, "here's my van, here's the awning, knock yourselves out" said I. An hour later, they admitted defeat & gave us a refund. Then we bought a Doreema, great bit of kit, but we soon realised that drive away awnings weren't for us, so that went too. Unless, (and this is purely my opinion based on experience, nothing more) you need the space and it has to be attached to the van, forget drive aways, they are a PITA. If you must have the extra space, buy a cheap pop up tent/shelter. We have a sun canopy that suits our needs perfectly.
Like I said, just my 2 penneth.
