Does anyone know if a sliding rear window can be added after market? To me, having one is half the fun of having a truck. I'd hate to pay 1,000s more for leather (which my wife hates) and a touchscreen that doesn't work well just to get it.
Anything is possible, with enough, time, money & effort. Being that no-one has really had a chance to look at the RL, either end users or most of the aftermarket. If it was me I believe, your most likely to have to buy a factory window, switch and possibly drivers door switch panel. Hopefully the wiring is already in place, possibly the drivers door switch panel has a blank plate, (easy to remove) switch should be relatively cheap (common) window will be pricy. I'll be shocked if the aftermarket comes up with something, but who knows.
Hopefully Honda comes to their senses, and atleast makes that an option or better yet moves it down a few models.
