Ive done the round trip Seattle to Denver, Seattle to Phoenix, Los Angelas to Detroit etc.. several times in vehicles way sketchier than that.
The two big things to consider are the heating/cooling and the brakes.
No matter what Northern route you take there are some pretty long grades to go up and down but it sounds like that is covered.
I would take a spare ICM and a spare coil and know how to change them ( both are easy)
Aside from the normal road trip stuff I would take a fully charged battery jump box.
Keep in mind you can fix just about anything on these trucks on the side of the road and even the most Podunk parts store will have SBC parts.
Ive even put a fuel pump in mine in the middle nowhere by using the factory scissor jack to tilt the bed
My only other piece of advice when driving through the mountains of the west is to never ever check out of your motel room untill you know the road conditions in front of you.
Storms can pop up pretty quick and dump a lot of snow.
I neglected to do this once and spent the night on an offramp in Wyoming in a standard cab F-150 with a 5 speed and a no tilt column.
It sucked.
( take food, water and a damn good sleeping bag just incase)
Oh, and try to do the drive during daylight hours to avoid black ice and know that some of that route has a long long way between gas stations so keep er full
But, I would drive that truck to Texas no problem
