My TM (I'm the original owner) got hailed on a few years ago. I see it as "battle scars." You have to wonder if a prestine camper ever gets used.
(Just kidding - some people on this forum really love their TMs and make me jealous with the great care and talent they have in keeping a well used TM looking like it was sitting on the showroom floor)
It's a camper for me to enjoy - a few dings in the aluminum don't change that for me! So enjoy your camper!
