So, after a year and a half of considerations, and reconsiderations, we decided to trade in our 2018 Taco for a 2020 Tundra

The main reason is that we expect to be much more comfortable for long drives. Problem with the Taco is that you sit in it like a car. The Tundra has you sitting up with your feet down, like a Jeep (which I'd rather drive, except it won't tow our teardrop). We actually traded in the Taco, with 65K miles on it, for the same price we paid for it five years ago. The Tundra only has 23K miles on it, but we plan to fix that! Hope that the extra two years and low mileage buys us that much more time with this truck. Might be the last one we'll ever need.
With gas prices not quite as bad as last year, we hope that won't be too much of a problem. When we went to upstate NY and back to New Mexico, we had such a big load, we were only getting about 13 miles/gallon anyway. We're hoping with the bigger engine we might even do better than that.
The pictures from Carmax showed running boards. Not sure why they took them off, but they claim to be ordering some to put on for us. Carmax has really gone down hill! Their Service Department sucks!
We also need a Camper Shell.
Oh, the Taco navigation system was terrible. Couldn't compute the best route if you gave it two points on a reasonable state route. Now, they want to charge us a monthly fee for the privilege. Of course, where we drive, there sometimes is no cell phone service, so Google Maps won't work there. Guess we're back to Garmin.
