They do make a power rear slider cause I have one. It's been in for about seven years and the only problem I've had with it was a new switch. Which of course they didn't sell alone. Had to buy an entire wire harness to get the same switch cause I had mounted it in the dash and could not find one either larger or the same size to go in the same hole. I think the wing window idea is a winner. I gotten so use to opening the rear window for the dogs, I have a cap, mobile kennel and six labs that allow me to go for a ride in their truck on occasion. It been well worth it for me. Because the rear window in my truck was glued in, no rubber gasket for this install, I thought that I had gotten in over my head but everything went alright and have had no issues with it, though it was a PITA. :-laf
