Inflatable awnings

We have bradcot 390, very pleased with it, it has multiple points where air can be put in but one point fills the whole system. It also has the benefit that you can add extensions to it if you want to have an annex for instance. 

It is up in minutes. Quite heavy to carry around though. 

Having watched numerous inflatables  being "deployed" the things that puts us off getting one,

1 the weight of quality makes to carry and thread into awning channel

2 the amount of pegging out (more guy ropes)

3 the times we have seen in wind  they tend to "collapse" 

Upside no "poles" 

Yes quality ones are heavy and not cheap but I have been impressed by their performance in very strong winds. My Kyham could not take a recent blow, two bust poles, one joint just snapped and one alloy pole just bent and snapped when attempting to straighten.

A Dorema near me never even buckled although one of its strap attachments broke.

pèedee.

What are they like in very cold weather, I have read somewhere they start to deflate?

The heavy ones are not a problem to thread into awning channels. My partner did it with assistance if a 12 year old at Chatsworth last week. If they do collapse a lithe in the wind or cold is only a little and takes seconds to recover with foot pump or electric pump. 

Speaking to some  one who has one they are suseptable to temperature fluctuations and care is needed at times as if you inflate to compensate for low temp inflate pressure reduction (overnight?) then they can over pressurise in the heat of the day and possibly split the "poles"

Interesting to see that happen in the U.K.  Lol. I guess it's possible but unlikely. The benefit is the speed of erection😉 Deflation and the lack of poles that will damage the van. Personal choice but we live ours. But yes they are expensive.  

Just like your vehicle tyres do, and what do you do about that? 

Completely agree, our replacement for our 260 all season Dorema will be a 330 Bradcott.

Even the 260 Bradcott dwarfs our 260 Dorema inside 

And top quality material too!

And Made in England!!

I have bradcot aspire and have never used the guy lines yet.
