Yes, the battery is a Sears Marine battery, the expensive one on the Sears website. The charger is one of the less expensive Sears models, probably around $49. The charger plugs into an outlet in the wall and is simply wired into another outlet on the outside of the trailer. I have no service panel in my trailer, just two outlets on the outside that power a total of three outlets inside the trailer, no breakers either, real simple set up. The lights are florescent, two of the small ones, about 14" long and the vent fan is an auto fan like you would find under the hood of your car mounted to my back wall under the hood. It is a pretty simple set up and will run for about 8 hours on the battery alone.
As far as the Yamaha generator, it is very quiet, cannot even hear it inside of the trailer when it is under load. If you are at my window, you may hear it, but it is rare to even know that it is there. I have people stopping almost daily just to ask about the generator as they are totally blown away by how quiet it is. And what is nice, is that you can buy two of the little EF2000is Yamaha generators and link them together which gives you the ability to run up to 4000 watts of gear. I just change the oil on a monthly basis in mine and she runs like a champ.
The contents of the fridge, they stay in the fridge. I just got home and pulled my two pans and utensils to wash, dragged out the garden hose to fill the hot and cold water tanks, rolled the hose back up, backed the trailer into my heated garage, dropped her and plugged her in. She is nice and toasty for the night and out of the elements. Right now it is in the 20's here, around 55 in the garage, been in the low 20's all day with the wind chill. Still managed to eek out around $18 an hour net, beats working.
