I have a Llama with an attached spray deck for sale. The spray deck is from '05 or '06 - it has one inflated chamber that wraps around the opening with a flap that comes over the opening and velcroes closed; it also has some stiff material at the top of the opening to help keep the spray deck convex.
There are pictures of it here (it is the greenish one with the orange spray deck): http://www.jtlindholm.com/day_21.htm
I will also include an inflation bag with the purchase.
The floor will need some attention. It has wear spots (pin-holes) where my heels and butt hit the occasional (HA!) rock. These can easily be fixed with some aquaseal or by applying some floor material over these two usual high wear areas.
PM me if you are interested.
