I have a 1988 Winnebago 37' Elandan with dual Coleman model 6779B installed. Both units are acting the same, both will trip in the heat of the day (100-105 degrees). They run great in between 8pm-11am, but after that, they will run for 10-15 minutes, trip the breaker, leave them of for 1-15 minutes, then reset the breaker and on goes the cycle. Anyone know about this?
