Unknown battery drain

So I have a 2001 prowler northwest edition with an unknown battery drain. So I pulled every fuse and tested amps and got zero across the board. Unhooked the grounds on the battery and got about 8.2 amp draw everything off this includes antenna booster, LPG detector and climate control in the fridge. Any ideas what I can check and where other fuses are located besides the ones in the fuse panel inside the rv?

Thanks in advance

    Wow - 8 amps?? Thats a lot.
    Any chance there's a light or two on someplace in a compartment? Or tank heaters?

    Agreed 8 amps is too way too much. Do you possibly have a light on in a storage compartment?

    Try hooking up your meter to read 8 amps and then pull one fuse at a time until the amperage drops. That will at least give you a starting point.

    I am guessing the emergency brake pull away switch!

    Go out and check it quickly, before the magnets overheat (well if the ground is off, no problems. )

    Just push the switch back together, and the amp draw should go away. It is about the only thing on the RV that is not fused.

    Your CO detector might still be plugged into one of the fuses, but probably only draws about 0.01 amps or so.

    Good luck!

    Boy do I feel dumb I forgot I accidentally pulled out the breakaway switch when I unhooked and I just left it. I hope I didn't screw up anything

    How long was it pulled with the batteries hooked up? I'm going to bet you're fine though.
