Expected current draw should be?

I have never been happy with battery behavior in my 2011 Greyhawk 31DS, although some of the problems may be my fault. I recently replaced a type 29 wet cell marine battery with a Trojan 24AGM true deep cycle battery (the 27agm was too large to fit). I fully charged the new battery and installed it. Taking my trusty Fluke multimeter I measured current draw with the battery cut-off active, and the current was 3 milliamps (.003 amps) which seemed OK. When I then pressed the cut-off switch, the current was somewhat variable, starting at around 2.25 amps and stabilizing after about a minute around 2.5 amps. This seems like a heck of a large draw with no lights, fans, frig, or anything else I can think of turned on.
I hope to hear from some of you about whether this is a reasonable draw or not. If not I plan to start pulling 6V fuses to try and find out what is causing the load.

If I had anything better to do I would be doing it :)

You have the coil in the 12v relay, the LP detector, the electronics in the converter just to mention a few. Also is your antenna amp or off?

Here is typical 30AMP Power Distribution Plan - Maybe something here will trigger some thoughts on what might draining parasitic type drains... I see 1-2AMPs from parasitic drains with my 30AMP setup all the time. Comes and goes.

Stereo, CO and smoke detector will be drawing some. I have 2 thermostats that are electronic and will consume as well. Does the water heater have a paracitic use as well?
