Hello All, Just joined as I have been looking round for tips on installing a bike rack on my 2009 Autocruise Startrail. I have a fiamma pro C and have just received the rear panel diagram from Swift. There is a 28mm plywood block for the bottom brackets, but no block to support the upper brackets for this model bike rack. The upper and lower brackets are spaced from 400 to 500 mm. What amount of force/weight are the upper brackets subjected to? (Max 40kg load on bike rack) As the upper brackets are behind the fixed bed headboard, can I strengthen from inside? Any help greatly appreciated.
