Scott Somers Shows us Around “Elle”

Part two of a three-part episode featuring Scott Sommers taking us on a tour of his 1974 GMC Motorhome.

Some of the Equipment seen in the video

Scott was kind enough to respond to our followers on social media who had asked for more information about some of the equipment featured in this episode.

1800 Watt Planet Audio Anarchy Sound System

The subwoofers are two of these:

Mounted in these 8″ Subwoofer cabinets:

The center channels are these: 

And the rear speakers are these:

And the front (over cab) speakers are these:

According to Scott, “I also used additional speakers directly behind the front seats at floor level, and the original “center” speakers were Infiniti speakers, but I don’t have data on either.  I installed an additional subwoofer under the kitchen, but again, I don’t have the data on it.”

Marine-Grade Latches

“The marine latches are these and I highly recommend them”, says Scott.

“Although I didn’t install them myself, the door and drawer pulls are of the following type”, says Scott:

House Battery and Charging System

Scott uses a large lead acid 8D flooded lead acid battery of the type seen below:

He charges it with Renogy solar panels.  “It will run a microwave or hairdryer, and is entirely sufficient for boondocking and is very cost effective when compared with lithium or AGM”, according to Scott.

Scott notes that “the inverter/converter is a Xantrex Freedom SW 2000.  It performs well, though as noted in the video, there is no way to turn off the cooling fans when connected to shore power and it is “converting,” so I installed a disconnect switch. “
