Every site we have been to we cannot get the a/c to stay on the first few hours or evening.After we get past the the first few hours in most cases it is fine the rest of the time.

Turn off everything except the A/C. That means the converter (which is probably charging the battery and drawing 6 to 8 amps), turn off the water heater (drawing 10 amps), and put the refrigerator on gas (saving about 5 amps). I bet this solves your problem.
