Spreader bars are provided to support the annexe roof on the Kimberley
Kamper . At the camper side, the bars fit into sleeves sewn to the annexe
roof. This arrangement works ok, but we found that it tends to pull the
roof down on the zipper and looked like it might cause a problem with
purchased three pole brackets from Whitworths - the front two are screwed
through the canvas into the internal frame, the rear one needed a backing
plate since it didn't line up well with the frame.
We've used this a couple of times and it seems to provide better support
for the annexe/ roof and gives it a better shape. Also means there's less
need for ropes for short stops (provided no strong winds).
