Good luck with it. I know how it is to want one of these things. I wanted one for many, many, years, and for one reason or another, I never did build one. To top this off, I am a Carpenter.
Well, I finally decided enough was enough. I built mine and never looked back.
I'm sorry to say, but your wife is probably right. You will live with the truck for awhile. It's nice to be able to tear it apart and leave everything laying right where it fell, if you like. I'm a neat freak when it comes to my stuff, but sometimes, after working on something for hours, you get tired and say, ahh, it's fine until tomorrow.
A man and his shop. It's a beautiful thing.
