Thanks Nick and Andy. The icamp mini is almost the same width as the Skycamp so not much point I think - it’s the width that I think is the issue on a 120. That’s where the xcamp would score as would fit well within the rails width wise. Would be different of course if I had a100 or 200: now there’s a good reason to change!!! Anyway , given the cost , I think the sensible thing is to wait until Lockdown is over so that I can look at them all in the flesh. There are some good images of a Skycamp on a 120 though in the Dubrovnik 2018 thread in the travel section of this site- thanks to Rosy for the pointer. Great help as ever here.
