Well, it looks like you found the problem - the pickup. But introduced another problem along the way, which you solved. Well done!

I hope the run with the trailer goes well and you have turned a corner.

I hope it is the right turn and not into a wall

I am running out of things it could be, to the point of thinking about HEI dist.!

Good news it is fixed!
Pulled the trailer 20 miles to the cruise with no issues.

Talking to a member on that other forum kind of had the same thing happen.
The star wheel was hitting the coil.
I think the pads missing let the coil move all over causing the miss leading to the bad #4 plug and bucking.
Being the new pickup was hitting the coil and it would not take any throttle with out bucking was a clue.

We are good now and hope for another 28k miles

This is what I pulled about 20 miles each way.

That's a pretty good load, regardless of what's in it. At highway speeds it'll have quite a drag. So the fact your truck pulled it well says you got things sorted.
