The first one of these types of ladders that I've owned. Wanted an all purpose ladder that I could load in and out of the back of a long-bed pick up truck with a cap and not have it stick out the back. Looked at, and was very impressed with the comparable Little Giant ladder. It was also well made and had the same capabilities as the Gorilla. The Little Giant had only one feature that the Gorilla didn't, wheels built into the base of one end. That was a feature that I really didn't need, so it didn't come into consideration. I decided on the Gorilla number one because it seemed just as well made as the Little Giant, but more importantly, it was about 1/2 the price of the Little Giant.
Being a painter by trade, I use ladders daily. And the Gorilla's been everything I need it to be. It's easy to unfold and extend. It feels safe when you're on it. And it collapses into a relatively compact package when you're done with it.
