Just happen to have a Bradcot brochure here I got earlier in the year. Can't find 910 in the sizing guide, there is 915 listed which has a range of 909 - 923cm, and a 900 which has a range of 886 - 908cm. That's about as helpful as I can be.

To put it into perspective, 910 cms. minus 900 cms. = 10 cms. which if you check on a rule is about 4 inches which is just two inches either end of the caravan. It's better to go slightly bigger than smaller anyway just in case the ground slopes away from the caravan door. If the awning is too small the material won't reach so from experience I would say that a size 910 cms size would be a perfect fit. If the awning is slightly slack you can always use a pair of ramps under the caravan tyres to gain a little extra height if necessary.
