had sliding windows fitted by Mak"s caravan repairs in Toowoomba . I don't recommend them as they fitted them upside down ????? but they just might be able to direct you to their suppliers.
Mine is t1n window on sliding door & main rear window . Good luck .
They were available before from a Bris based co. Cant think of the name offhand. But they have no more & I guess that model is getting a bit old for them to bother stocking them anymore. Rocking horse biz now
Found. I just scored a pair of long side ones for $240
Paulmelb I found another , I believe its the RH, long rear side window for $400. Let me know & I will point you in the right direction
Still looking for Rh sliding door, sliding window
