I'm on my 2nd. Bought my first one used, liked it so much I traded it towards a brand new one. Super comfy, both the drive & the interior.
Very good value for the price, even better value now that the new ones (supposedly) will be coming out. I wouldn't buy the new model for at least 2 years (goes for any make).
Proven drive train. 13' & up can have OEM back-up camera, very nice feature. The OEM navigation is ok, aftermarket is better.
However-for about any type of "gadgets" you feel you would like, pop in a new head unit with whatever gadgets you think would be handy. Can easily add in a backup camera as well.
Thirsty? Yes definitely. A bit bellow the same "real world" mileage as any full sized pickup, however a lot more fun to drive. Stock & loaded up for a trip with family & gear expect 12 highway. Towing expect 10, perhaps 8 if it's a big trailer. Around town, stop & go traffic only expect 10. Adding bigger tires, armor etc? Expect lower mileage. If you can deal with that, then absolutely it's a great truck.
Limited aftermarket support, but enough for anything you would want to do overlanding wise.
Be sure you can deal with a 5.5' bed if getting a crew cab. I think the Kings still have a longer bed, but then you lose cabin space. The only real reason for a longer bed would be for a slide in camper, however halftons aren't meant for today's slide ins (FWC & the like excluded). If your future plans might head towards a slide-in, then this is really the wrong class of truck. Look at 3/4 & up.
Towing, however these trucks can haul about anything you'd want a half ton to do & all day long.
