Continued working the interior, starting with the trunk area. I framed out the battery box area to hide it from the trunk side. If you're wondering why the heavy lumber, I used what I had lying around. It won't be seen once the sheathing is installed. The rear seat back folds down so you can access it from that way.
The last shot is all the material fabricated to close in the trunk area. If it looks like a lot of material you're right.
Added Fatmat to the floor to provide some insulation and sound deadening. This stuff is less than half the price of Dynamat, so if you're looking to cut costs this is a good alternative.
