Yes I gathered. But since you mentioned power usage the type I posted are the most efficient you can get due to the box design and the fact cold air falls. So the typical door type the cold air falls out and then needs to use power again. I have a big boat and could have gone built in also but I suppose if you want built in then its of no use to you. Yes I do love the seating on those boats very nice, been looking at those boats on the auction I shared and its hard not to put a bid in
