I must admit, I do like our Outwell. Bought a front extension for it so lovely amount of space, and can sit under cover whilst it's raining but still be outside in teh fresh air, if you see what I mean.I’m in a similar situation to you. I was thinking about replacing our 8 man palace with an inflatable job but can’t really justify it. It’s only a few years old and there is absolutely nothing wrong with it.
A mate and his new bird came up here recently with an inflatable one. Can’t remember the make or model but it was a decent (expensive) one.
They only stayed for one night. The thing deflated with them in it and a thoroughly shit time was had.
It also didn’t appear to be that much quicker than normal poles. Took quite sometime to inflate and he wasn’t close enough to his car to use an electric pump.
