Definitely interested in hearing reviews. I am currently researching lights and am leaning towards the towmate RVHW32 and plugging it into a jump starter with a 12V outlet that would sit in the bed of the truck. The cost is a lot more than wiring the truck lights but my Ford dealer warned me that if I cut into the factory LED taillight wiring I will void the warranty (probable just a threat but I am not willing to take the chance).
I use my current jump starter to power my enclosed trailer and it will last 3-4 days so should be no problem powering the tail lights. I was concerned that the battery powered lights might not make it through a trip without needing to change or charge batteries.
Also interested in how people are mounting them. I may have to build something or maybe use the suction cups as I just have plastic and aluminum to attach them to.
