Runaway Bay Qld store. About 3 left.Probably Australia-wide. maybe call ahead to confirm.
4850x2600x1900. No pump included. They look good. Were $299. I always use Waterproofing-spray on the whole tent, especially seams, for peace of mind. And if it leaks on the first downpour it goes straight back for a refund.
Try making a solution of a white spirit like turps and silicone. Paint it on the outside, maybe 2 coats, and you will get great waterproofing especially in seals.
The spirit liquifies the silicone, then evaporates.
