Excellent!
Make it as big as you can afford plus some more.
I hope you are allowing for a toilet and shower with fridge??????
If you are married, do you think your significant other is going to let you near the house after working on your truck when you are all greasy and dirty?????
I speak from experience!
Add lots of electrical plugs everywhere, Lot of power including 220vac. You will only get one chance at it. Add lot of lights. Add insulation. Add utility sink. Add stereo for tunes.
Make a big sturdy work bench tied to the wall and floor (4' x 10-20' long).
Add lots of shelving (heavy duty).
Add cot/bed when your in the dog house.
Add couch for you and your buddies to bench race and drink beer.
Add big tall garage doors for the next bigger truck you going to have, unless you already a semi truck?
Now, the real question is how do I know all of this????
I am doing it again (2nd time) on my property in OR.
50x72x2 story on large piece of property
Still trying to do it right. ?:{
