This is a typical trailer hookup mounting the INVERTER in the pass thru storage area very close to the 12VDC batteries... I use the PSW type inverter here so that I don't ever have to worry about plugging my expensive home entertainment items into the inverter 120VAc source.
I started out with a 300WATT Inverter setup in my OFF-ROAD POPUP setup but kept adding more items to the emergency power source and finally ended up with a PSW AIMS 600WATT Inverter. I have two 120VAC drops here one going to the home entertainment area ad the other going to the tent bed table top. Always have something 120VAC you want to plug in hehe... All that is visible is the multiport 120VAC receptacle at these locations. All wiring is inside WIREMODE duct work.
