.... Very Carefully, Nate!

As I understand it, propane tanks need to be purged after several years to
remove sediments/gunk. Many RV dealers will do this... or a propane
dealer... there are also shops that will completely renovate your tank...
they sandblast and paint and purge and clean the inside... might be a good
time to do the?
