Your trailer is designed for 30 amps max. Two Honda or Yamaha 2000 watt generators will be all you will need, as well as a parallel kit. You will need both for the a/c, the rest of your things will run on one.
They are very portable at 44 lbs each. I like the Yamaha gens as they have a fuel shut off which allows the carb to run out of fuel to keep it from being gunked up.
Got mine at Wise as well.
