I bid on a few 48" Hi-Lift jacks on E-Bay and didn't win. I was assuming they would be "big enough" for my uses. Then I submitted a bid on a 60" AllCast and won - for less than what I'd bid on some of the smaller sizes. I thought I'd made out like a bandit. When I received the jack I found out this thing is a beast! It is very big and fairly heavy, although not unmanageable. It'll be a pain to mount and unmount once I get the roof rack mounting setup. Also - I don't think it fits very well mounted across the back of the rack as some have done. Now I kind of wish I'd gotten the 48", but I'll make do! :bigthumb:
