I demoed out the entire drivers side of the rv, spray foamed behind where the main equipment rack would be for r-value and sound dedening of the outside world. Meanwhild doing my best to fabricate the 1st cabinet carcass. To work with the curves.

pita! LOL
After the spray foam high wore off I figured out my sound panels and how I would make them. Then I moved forward..
Attachment 1: partial demo
Attachment 2: packed with oc703
Attachment 3: upholstered
After 4 trips to fabric stores I finally found a nice fabric to upolster the first side. I think I bought enough to do an entire house to be safe!
CHeerS!
more to come...
