no such thing as "crazy" to lend someone your gears; most of us do so if we trust them that they will take care of your stuff as much as they were theirs.
I once lend my 1D3, 17-40L and 24-70L to a friend who happens to be on vacation to Paris (winter time) just because he is not comfortable using his 400D in such conditions. Am I worried? Not at all as I trust my gears are in good hands.
They all came back in one piece though, my friend was even kind enough to send my gears to CSC for cleaning/ maintenance checkup before he returns my gears to me.
