I too bought a Tundra in the last few weeks but not the double cab. Mine is whatever has the shorter bed and four full doors. My only complaint so far is the TRD exhaust is surprisingly loud for a factory exhaust. it can be heard by the other party when talking on the phone using Apple Car play.
The gas mileage is not great, especially when towing, but not significantly worse than my 2014 F150 I traded. I loved the Fords in every way except reliability. Hopefully, the Toyota is better. So far, I like mine.
