I have the Blue Sea ACR hooked up in my Tundra with a Bussman CB185-150 150Amp Circuit Breaker. I ran a 6 gauge power lead back to the bed of the truck and attached some quick connects to it so it would handle my dual-battery setup (Optima Yellowtop 27). My ARB 63q plugs into this 2nd battery in a battery box via the cigarette plug. Everything worked fine especially driving through 100+ temps through Bakersfield last week. Fridge was set to 34 and it was at 32 or 33 most of the time, this was in back of a pickup with a truck lid on and packed with gear. My problems started 2-3 days later when I was at campsite and my Powerfilm 60w could not keep up with the demands of the ARB living in a Bear Bin when outside temp was mid-80s, much hotter in bear-bin. Going to upgrade my Solar panels to 200W with an MPPT controller and give it another run at it.
The Blue Sea gear rocks and it kept my Aux-battery at 13v for the 6hr drive.
