Karsten were the first inflatable awning of any quality that I'm aware of. I believe they specialised in tents, some of a modular basis that you could add to as the family grew. Such was the quality I think they would at one time by back in your old tent. The quality is superb, but new they come with a price to match. This is reflected in the final fitting/tailoring service offered of your made to measure awning. They are heavy, I think 40kg would be a reasonable expectation for a Troll awning.
