I have just put the Twinkle in the new
garage, we put the ridge on yesterday, but no door for another couple of weeks. We thought we would have to remove the aerial but himself stood on a ladder whilst I reversed her in. We have about 80cms to spare at the back, so a baulk of wood fastened to the floor at stopping point sounds a good idea to me. I have about 6" clearance getting in, but can open the top hinged garage doors once inside.
