My trailer is all electric except for the wood/charcoal smoker and propane stove/turkey fryer.
I’ve got a water pump, heater, fridge, 3 hot food wells and 1 double cold food well, stereo, lights. Everything running I need 10KW. I’ve gotten by for 5 years with a 3000W quiet Honda and couldn’t be happier. All you have to do is juggle your usage and keep the surges in mind.
It’s great to have a 220V 50A hook up, but you can’t beat the size, portability, fuel economy, reliability and most impotantly the quietness of a Honda or Yamaha type gen. When I first started I bought a big boy gen from Lowes and returned it within a week. Drove me crazy!
I recently added a convection oven and will run it with a smaller 2000W Honda or Yamaha. I prefer to deal with and have more options with 2 small quiet gens than a big boy.
