Hey guys. I'm looking to install a dual battery system in my 88 ProStar 190. Anyone have any advice? (Any got-cha's I should be aware of)Specifically, a good location for the 2nd battery. Thanks!

Not sure if this helps, but it should get you the idea.

I put dual batteries in my boat and am using an isolator to keep the starting battery from being drained when the engine is off. Here are a couple of pictures that I took last night.
