A TV and trailer tongue loading...it is NOT a hard fulcrum like a teeter-toter, but compliance from the tires and suspension (AKA Squat) which adds another level of geometry to account for
Then the weight of the TV forward of the rear axle's axis of rotation. Does the OP have a standard half ton with short bed?...extended cab and that added weight...crew cab and that added weight and all of the options this half ton has up there
Another assumption is that, since the OP says 'strong' might mean it has the 6.2L, which is typically optioned with lots and lots of goodies
Hows about that 2" 'leveling' modification? What is that? Body lift, lift blocks on the rear axle, or ???
My first guess for a 2" leveling on an IFS GM truck would be a torsion bar crank/adjustment. Leveling is almost always a front end lift, since most pickups ride higher in the back from the factory.
