Have you found the packing slip yet? What does it weigh?
My Morton delivery weight was 48,579 pounds. I thought it was interesting because I spent a few years as a receiving clerk and a shipping auditor.
Interesting photo of perma column style post bases. Look like they are adjustable for setting height. I had name brand perma columns installed on my barn and they were not made like yours. I like the concept...post some photos of install technique!
