Would upgrading my stock shocks to the ACDelco Gold (Professional) Premium Gas Charged Shocks help with the towing experience of my travel trailer? I'm towing with a 2018 Silverado LTZ Z71 6.2L with ...

You're probably experiencing a porposing effect, I'd throw on a set of Timbren's on the rear. They are just replacement bump stops that are made to be used as a rubber spring.
I agree, 99% likely it’s porpoising, and most likely only on concrete highways.
d1h is going to have to provide more info before determining whether something like Timbrens would help or do nothing at all.
in order for them to help with concrete panel joint “harmonic” type porpoising he would have to have the rear suspension basically sitting hard on the Timbrens. Enough to help counteract the very small undulations.
But not knowing how much weight he’s carrying vs distributing makes it anyone’s guess.
Now if he’s carrying enough weight to produce some significant rear suspension travel over bumps (this doesn’t happen with just pavement joints on an otherwise smooth road) , then absolutely adding something to stiffen up the rear suspension is appropriate.
JMO and as often on here, we’re shooting in the dark with minimal info provided, trying to help someone remedy an issue.
I think what you are describing is probably what is going on. Newly paved surfaces are no problem. Patched areas and dips in the road surface is where the front end bounce happens. My truck has no rear end sag with my weight distribution hitch which is shown here. That's why I thought new upgrade from OEM shocks may help with the front end bounce.
