sides 920mm front 2010mm long. I cut about 50mm off the length to achieve this. I think jayco just give you a little bit extra for good luck. Just looking at the last long piece on the ground (last bit to rivet on) there is no bulk to them but could get damaged if not in some sort of protected tube, especially being loaded by luggage handlers .Best I order one then hey! Would you know the lengths they need to be? I can cut them to size which would make it easier when boarding!
