Just finished building my trailer a couple of weeks ago and Friday took it up north for its first camping trip. No shore power so I brought my generator. I have a rooftop air conditioner, Dometic Duo therm model 57915, 13500 btu a/c unit with heater. The week before after work every night I would stress test it with my 2000 watt Honda inverter generator for at least 2 hours. Without my fridge running the generator would make a little noise when the compressor would kick in but nothing out of the ordinary and would come back down to about half throttle shortly. With the a/c and fridge running it sounded like the generator was running at about 3/4 throttle. The first night fired up generator and was running a/c on medium blower with thermostat on coldest setting. Forgot to open the vent on the generator so it killed after about 5-10 minutes. opened the vent started back up and then 15 minutes later tripped the breaker on the generator. Restarted on low a/c lasted for 5 minutes. Let sit for 5 minutes restarted this time with a/c low and thermostat 1/2 way between cold and coldest, that ran for half hour went in and bumped up thermostat every 5 minutes until the thermostat was almost all the way to the coldest setting then it tripped immediately. Tried it again in the morning and it ran on low blower coldest thermostat setting and tripped the generator after 30 minutes. Restarted and tripped in less than 5 minutes. PLEASE PLEASE PLEASE i need help with this I am going back to the camper for my big trip of the summer Tuesday morning for 7 days. This is the trip that I built this trailer for, thank you in advance for any help.
Few more details
-Honda companion 2000 watt inverter generator 2 months old with little use
-Switched to buddies brand new Champion 3100 inverter generator and tripped his generator within 5-10 minutes
-Does not trip breaker in power center, breaker is a month old and tried switching with another 20 amp breaker with same results
-12-2 wiring with 20 amp breaker and off power center 30 amp plug 30 feet long
-Nothing else is running while I have the problem
-Ran dozens of times on high with thermostat on coldest setting with Honda generator
-I believe the a/c unit is from 2013, not sure don't know how to tell for sure but the inside plastic cover had a inspection tag on it that said 11/2013
-Running generator with eco throttle on or off makes no difference in results of tripping generator
Any help is appreciated Ive put a ton of work into this trailer for this trip and its a real downer not being able to use it to its full potential.
