thanks for the replies everyone. I think there should be a foolproof system where every tenant in every state provides a list of contents, signs, dates, and makes 3 copies: one for the owner, one for themselves, and one for the facility manager.
Two things going against this idea (IMO):
1) Nothing is foolproof.
2) If I rent a locker and list the following items:
a) Mac tool box with Mac tools
b) 42" LCD tv
c) 150 gallon aquarium
d) sofa
e) etc, etc
AND THEN....a month later I take out the Mac toolbox and tools, and a month after that I take out the aquarium
am I going to alter that original list (multiple copies) each time I take something out ?
AND....what about the new stuff I put in like the Harley Davidson vintage parts in month 3?
OK, now it's month 6 and I default....that list would be a nightmare to maintain (IMO).
