I wouldn't add any thing to a new truck till you load it up and make a trip. Then make your decision.
Camper struts were common years back ('60s-'70s) when truck campers far out numbered the all other RVs. I don't believe the new TC are any stronger in this area than some of those old units nor do they lead to less movement.
Most common was pickup bed stake hole mounts with turnbuckles or just bolted through the floor into the beds frame (not the trucks frame). This caused lots of truck camper movement as the truck bed floated around on the trucks frame.
Now .... the new trucks may have more of a ridged bed mount system over those old trucks.
Much depends on how the TC is attached to the truck.
