If you go octagon, one thing I would change is to do 6 sides all the same width but do the front and back sides half again as wide. This will give you a deeper tank and will give you more room for a double rack. Mine has 10” width x 48” length and I have a double rack. It’s pretty tight. I’d do 16” front and back instead and give myself more room.EverydayDiesel wrote: ↑November 21st, 2020, 12:03 amThanks for the replies! I really appreciate the help
