You know this issue of incorrectly labelled tank valves has been going on for years at Keystone.... Honestly there must be a few dozen threads about this problem.
I have to think there is a prankster at the factory who waits till the final inspection is over and makes the switch of the labels.
There is no other explanation, and you have to wonder what other "pranks" are being being pulled
I'm willing to bet there is someone who sprays "decal anti-stick agent" on all the logos just before the camper leaves the facility
