Thanks! Now that he's gotten this far with it I'm excited to start on mine as soon as I get the other buggy project out of the shop. I was honestly curious about how it was going to turn out getting all the walls in and solving some problems creatively... and now seeing it is pretty motivating.
Here's an update. Sounds like maiden voyage is coming up next month!
Doors and trim are set. I noticed there's a small gap in the trim on top, not sure what's up but knowing him he'll have that resolved somehow.
He also got the custom built trucker box installed. This is helping it look really complete. We should build a gear rack for the top of it.
