I just finished installing a 30A Progressive in my Sunseeker 2700DS. It was an easy install except for the tight space. I put it under the drawers next to the refrig. that is where the shore power - generator relay is located. I just disconnected the line going from the relay to the fuse panel and connected it to the output of the surge protector, and then used a short piece of 10-2 cable to connect between the relay box and the input of the surge protector. So now I am protected on shore and generator power. I installed the remote display above my CO alarm. I purchased this at Tweety's for $247.
