We left Zion this morning and are now at Lake Powell, Page Arizona. The temp is about 100 + or - a few. When I run down the road I use 2 cruise airs on the invertors and the dash air, no problem! When we are parked all 3 cruise airs are running with the temps set at 73, still no problem. I, like JDUB heve to keep the 3 girls and the wife cool, not an easy job but so far so cool.
