A while back I was reading about adding a 110v outlet in the basement compartment. We have the 3475 Model. One suggestion was to go thru the washer/dryer compartment. But that ment moving the washer/dryer. So, after aquiring a 12v fan for the bedroom and finding no 12v outlet nearby, I traced a route thru the hole that the water pipes come thru from the basement to the bedroom sink. I found that I could connect to the basement light with a wire and connector(fused)from CW. The hole was also large enough to snake a 110v 14gage wire thru it. I ran the wire under and thru the side of the chesterdrawers and pluged it into the 110v outlet on the side of the bedroom. The other end is connected to a multiple plug in the basement. Now I have both 12v for overnite dry camping and 110v for outside radios.
