I too just purchased a Venture Cat 15 a few days ago. It had been left alone outside for a few years but cleaned up better than expected. My main concern is the 1/2" drain plugs. It came with old rubber stoppers which weren't exactly watertight and one side has a crack that may have been caused by an expanding pipe test plug. What do your drain plugs look like?
Mine came with the old rubber stoppers as well. So far so good with them.
