Truck bounce
So we recently replaced our Envoy with a Tundra and towed with it the first time the other day. The ride was pretty bumpy on the way to the campground (60mph) but was fairly smooth on the ride back (4...

With only 1" of rear sag hitched, you may have an issue of TOO MUCH weight being transferred to the front end.
All these IFS pickup truck suspensions are similar, so I'd expect the Tundra to have "jounce bumpers" like most of the other trucks do. These jounce bumpers are essentially bump stops that engage at unloaded ride height and prevent the front suspension from compressing any lower.
No matter how much tension you put on the WD bars, the front end will NOT sink below unloaded ride height. So, you may think you've got it nailed spot-on, but you could be way overdoing it.
Try adjusting the bars so you only get 1/2 to 3/4 of the way back to stock ride height and see if that's any better. 1/2 is what manufacturers recommend these days.
Don't worry about rear sag. 2" just gets the truck back to level, and it looks like your trailer is riding nose-high anyway.
