Two thumbs up and a zipper snap
Oh and figuring out costs. The extra cost of doing 16" center studs will be made up in insulation cost. So 16" centers it is
Keep in mind that you're losing that insulation value. Framing lumber has an R-value of 1 per inch, while foam can give 4 or 5 R-values per inch. So a 2x4 gives you an R-value of 3.5 where you could have an R-value of 13-16 (depending on what you're using for insulation).
1.5" studs every 16" account for 9.4% of your wall area. On 24" centers they account for 6.3% of the area. So you're losing ~3% of your insulation.
Not sure if you care, but I wanted to point out the one downside.
I've had way too much time to think about this shop


I am as soon as I get this doneI saw the thread title and got excited you were building a truck to bring to Blazer Bash.....
Eric, your shop is friggin awesome! I'd love to have a space like that to work on my rigs. My Caddy just barely fits inside of my current shop.
When is the sheetrocking party? Are you needing help with your wiring?
Can't wait to see this thing get done. You need some work space and a place to organize your tools for sure! My OCD goes nuts every time I walk through your house garage. lol
Of course once I get my house built I'm more than willing to come help too.
