Recently purchased a 18.57-5 Expanda. Only done a few local trips around SA so far but the handbrake and I are loving it. A bit of a step up from our 1986 Jayco Swan! The only thing neither of us like is the concertina door to the ensuite. It is a bugger of a thing to open and close and I would like to replace it with some other sort of door. Has anybody modified theirs or can suggest a replacement type of door that is not toooo difficult to fit DIY?
