My wife & I took a visit to their showroom out Ipswich way last year & had a look at the F/Fold. It appeared to be made well but had a rather large tray setup on the rear which, in my opinion, would not last too long on corrugations & would also limit the departure angle considerably. I did like that the under body wiring was all in a protective tubing, not dangling for rocks, sticks etc to hit. It did have the I.S. with twin no name shocks & a poly block tow hitch (which may or may not meet ADR)
We also had a look at the Austrack FF at Caboolture & I feel that, if we were to purchase this sort of camper, it would get the nod. I can't put my finger on anything specific but my gut feeling was that there was something a little "Nicer" about it. Same poly block, by the look of it.
As it turns out, after looking at several brands & a lot of deep discussion, for the moment we're keeping our Goldstream Wing1 as the storage space/seating/comfort in the FFs just can't compare. Understandable by their general configuration & no criticism intended.
Good Luck with it.
