Auto-Trail post 2011 - Cycle Carrier options

I have bought an Auto Trail Apache 632, 2013 model, with spare wheel mounted on the rear wall of motorhome. This poses a challenge re attaching a cycle rack (for two bikes). There is plenty of room above the spare wheel, but, this would mean the bikes were mounted high, and I am no longer in the first flush of youth. So far, my options appear to be a Fiamma Rack, designed for the Auto Trail, a Wind down Rack, or a more radical solution, a towbar with platform on which to mount the bikes. My local Autotrail dealer is recommending a wind down rack, this is significantly more expensive than the "fixed" rack, and, although I may be being cynical, I have my doubts... Has anyone out there got an Autotrail, with rearwall mounted Spare Wheel?, if yes, have you a cycle rack fitted and what is your experience?  Thank you in advance
