The stepping pace can be a very smooth gait. I suspect on this horse it is very smooth as this horse is not being held up overly high in ventroflextion of the back and there is some element of a relaxed flow to this horses gait.
Valucraft, Duralast, and Duralast Gold are AutoZone's private label brands for lead-acid automotive batteries (manufactured by Johnson Controls, East Penn, and other manufacturers).
The AutoCraft battery brand name is owned by Advance Auto Parts (AAP), but AAP does not manufacture batteries. There is no large plant somewhere owned by AAP making them. The plants exist but are independent battery manufacturers, including GNB (formally Gould National Battery), and Johnson Controls Inc. But other more localized and smaller manufacturers also contribute to the demand created by AAP's 3200+ retail locations.
