I promised to post pictures of this install and never got back to it. I mounted the inverter under the dinette seat behind the electrical panel. I got a 60 amp toggle switch and and 60 amp inline fuse. I wired it off the DC Panel and instead of installing a cutoff switch to switch between shore power and the inverter I installed a dedicated plug for the inverter. Here are the pictures of the install.
The duel battery setup worked just fine for out two week vacation this summer.
The inverter installed on the partition between electrical and water pump area and pass through storage.
I picked up the 12 volt power on a spare lug in the DC Panel. It is Red Wire on the left on the bottom left of the picture below.
I put in an inline fuse
and ran it to a 60 amp toggle switch mounted next to the electrical panel.
And I installed a 115 volt plug under the dinette.
