Hi all, I read some threads about which vac people use and it seemed that the 1 gallon shop vac was a favorite. Well, my Walmart only had the 1.5 gallon model, which is a tad larger. When I got it home I noticed that it had a discharge hose port, just like larger models. Today I used it to inflate my 12' inflatable and it took about 3 minutes total. I also used it to deflate the dinghy and it also took just a minute or two. One big advantage to using it for deflation is that your can reduce the size of the rolled-up package by quite a bit. So, I can carry the dinghy to my boat and inflate it on the dock, tow it on my 1-4 day cruise, and deflate it again back at the dock.
I am always looking for an easier way to do things so I thought I would pass this along. It just occurred to me that many of you probably already do this. If so, please disregard.
