Electrical:
While there is plenty of useful information on the forum and elsewhere about building a power system, batteries, inverter etc., I was still a little intimidated and was looking for something much simpler. After doing some research I decided on the Kodiak lithium ion self contained unit. This was exactly what I was looking for, easy to charge, portable and compact, nothing to build, simple. An added plus is that I could use it to run some of the household appliances in the event of an electrical outage. Yes it is a little pricey, but in my mind well worth it for the convenience and time saving. We have minimum electrical needs and I don't see that issue changing. Plus if I need to add more power I can simply add to the Kodiak.
We have minimal needs and low power draw. Dometic CF25 cooler, LED lights, coffee and possibly a microwave. Thus far the Kodiak has served us well. Another shout out to Gary BIS and his excellent "Build a Green RV" site describing in great detail how to determine your power needs, wire sizes etc.
Our set-top has three LED ceiling lights, two under counter LED lights, two over the bed reading LED lights, MAXX fan, in addition to the cooler, coffee pot and microwave.
This view shows the installed lights. The back set of overhead cabinets on the drivers side haven't been installed yet.
The fuse panel for the 12V LED lights and the fan is in the center pillar.
The Kodiak is secured with threaded inserts in the plywood floor and threaded rods. The black electrical line plugs in to the 12 V outlet in the Kodiak to the fuse panel and the white electrical line plugs in to the AC outlet in the Kodiak and powers the two outlets above the galley cabinet. The Dometic cooler rests secured between the seats and plugs in to the Kodiak.
I am very happy with this set up and thus far has performed well.
