There is a real time video of pulling them out of the truck and installing them. Looks like about 15 minutes. I doubt they one guy could handle them to put them back in the truck though.
The company my father works for on the north slope just got some to do some durability testing on them, I will ask him if he has had a chance to use a set yet..... I totally agree I bet them would suck like no other to get stuck with...
