Very sad to hear that. Love my old 39 litre!
If I hadn't found my Autofridge on e-bay my research was leaning towards a Bushman package, with the waisted lid, extension collar and insulation bag, to give greater flexibility.
Another plus down here is that they are distributed from Melbourne.
If money, and spac, was no issue I would probably go a Trailblazer, but probably a bit OTT unless doing long extended trips in the tropics.
