My Y is actually the replacement for my R1T order. I was waiting on the max pack, which likely won't be delivered until next summer. We have kind of aged out of the need unfortunately. I'm still holding the order for now because.. I don't know why. Maybe I'll change my mind or something, but I doubt it. The efficiency (or lack thereof) of the R1T bothers me enough that I think I'd only use it when absolutely necessary for hauling or camping and drive our X all the other times.
The X does a perfectly fine job of towing and it's a good daily driver as well. They say you should never buy a tow vehicle that doesn't also function well for your daily needs, and since I'm efficiency-driven, it kind of precludes the R1T. I think.
