Thank you for the response. I am part of the old school for putting ground cloths under the tent. My tarptent already has a bathtub sides on it.

I would expect Philmont to want ground cloths under their tents to help them last longer. We are bringing tyvek ground cloths to Philmont. Two weeks from now, the crews will have spent the day visiting Garden of the Gods and Air Force Academy. Ready for my third trek (1982 ,2013 and now 2019)…..
