Mine do not power-fold but I am fairly certain you can get them in power fold as well. Apparently if your truck did not come with power fold it can be difficult to add them and have them fully OEM operational. A few members on here have added their own aftermarket switches so they could upgrade to OEM power fold side mirrors. 1A auto also offers power fold aftermarket tow mirrors that look just like OEM and come with a kit for wiring up the power fold.
If you do not currently have puddle lights and turn signal indicators, and change your mirrors out to tow mirrors that have these getting those to work can be a PITA as well.
1A auto is a preferred vendor on here and Tony can answer many if not all of your questions.
