Which awning room

Silver Roamers

I have a Swift Sundance 530LP motorhome and wish to fit an awning room.  One option is the Fiamma Privacy room which has good headroom but is heavy, the other is the Kampa Motor Rally Air Pro 260 which is lighter but has a possible problem with conflicting
with motorhome door as the distance between the head of the door and the awning rail is 80mm.  Any advise/experience would be appreciated
