There is a thread on here that discusses the testing of Toyota trucks vs. other trucks, including the F150. These were more structurally oriented, but I was blown away by how flimsy the Toyota frame was compared to the F150, and of course the Raptor is further reinforced beyond that. I assume you are thinking more in terms of powertrain reliabililty, but structure is relevant as well. Anyway, from what I have read, most of the issues you hear about on the forums have been worked out (fixed) in the 2019, and the 2020 will be in the same position. Given how much nicer and cooler the Raptor is over the Tundra, I think it's an easy call.
