I run the ARB chest/frig. It's awesome. I don't run an inverter (doesn't make sense to me to convert to AC to convert back to DC anyway), plus a good amount of energy is lost to heat with an inverter. That said, I have a dual battery system with a pair of AGMs, no isolator. I can run my frig for 5+ days (before it goes into lower power mode to prevent draining my batteries too much), kinda cool. In the future I'll have something to prevent depletion, but haven't needed it to date...
