Yes, if I had bought one for use on the trailer only, I'd have opted for a shorter one, but, I'd probably have gone with a 10' model. I already owned the 12.5' model for use around the homestead, so, it got additional use with the trailer. They are a tad heavy, but, collapsing like they do, certainly makes it much easier to store than a full sized ladder. With my 5er, I carry a 7' folding step ladder that I use for cleaning the nose cone of bugs or washing the side windows. It is one of those that folds up so tight that I carry it inside the rear bumper. Nice ladder, but, not tall enough to get on the roof, though.
