It will flex more when loaded. I am surprised how stiff the Gladiator frame is in comparison to my Tundra and old Ford F150. I didn't measure the flex with those trucks, but you could easily see it when off road.
I think all the < 1 ton trucks have a stiff boxed frame these days... except for Tundra and Tacoma. The new Tundra will be boxed as well.
I'm surprised yours flexes that much. On my Tundra the difference between the cab and front of the bed is small, but there is a lot along the length of the bed (it's 8').
