you cant buy it seperatly anymore,they come with the house this year. I have checked every where around where I live, plus on the internet. I called Frabill today and left a message, hopefullly they will call back next week. If I cant get the seating system, I will just sell my icecruiser 200, and get an otter or clam and say the heck with frabill for screwing people over, but hopefully they will make them available for those that bought a new house last year.
