One thing I have to worry about when buying a ladder is the load rating.. I'm 320 lbs dry, Most laddres are rated aroudn 200 lbs, Some 250, I think the Little Giant is rated to take more than I weigh.
Also, Most laddres will support a bit more than the label states,,,, However don't count on it.. I've one ladder in my garage just now I'm going to have to SERIOUSLY reinforce before Ican use it again... Unless I use it for halloween decoration (It's good for that) And I've purchased a 275 lb rated Fiberglass ladder that fits in the rig as well as a 250 rated (350 capable) "extension" ladder (Worst that will happen if it can't support me is I won't be able to store it and will have to trash it) Design feels like it could take 500 lbs w/o tbl)
I've looked at the Little Giant but am not sure how well it will store (hope to see some in QZ) and the cost is still a bit high.. Local ladder place carries them though so I don't have to go to CW (Which also carries them, same price)
