Little update, as I'm heading out on her maiden voyage in a couple of hours... I took the propane tanks to the wholesaler, and he took one look at the tanks, and told me he could not recertify them because they were from 1988, so they were too far over age to recertify. He did fill them both for me "this one time", so they are full now, but once they are empty, I may have to pony up for new horizontal tanks... I'm heading off to camp in a couple of hours. I will be sure to take lots of pictures.
