When it comes to choosing an awning . Just measure around the track and go pick one you like, easy . I've been looking on line, reading various threads on 'Fun' , but I'm none the wiser, well maybe a bit but nowhere near to choosing something as yet! Will it fit my Fiamma 3.5 track ? Will the habitation door clear it or open into it (door opening only 1'2" from end track) ? What about the gap down awning sides due to Fiamma sticking out 6" from side of van ? We're going to be wintering in Spain and staying put for three months so I figured it might be a useful addition to our modest sized van. In all honesty I can't say I much like the modern trend of lightweight drive-a-way or air awnings, and from what I'm gathering they are not really ideal for 'long term erection' or the Spanish sunshine. Maybe it's the memory of those nice old steel framed awnings from our tugging days...but I keep being drawn to the likes of the Dorema Challenger http://www.dorema.co.uk/de/motorhome_annexes/challenger.htm I'm just put off by the weight of 28 kilo and what I'm assuming would be a pretty hefty couple of storage bags to loose somewhere! Oh well, got until November to find something at least!
