It is your call but I have Chevy 2500HD with same specs as you rig and I use our hitch for the sway control it provides, not so much for weight distribution. Wind blows pretty hard in our neck of the woods, along with the mountains and valleys that add intensity when funneling them across interstates, need our sway control for those sudden gusts that want to push us off the road.
TT is a bit longer and heavier and our truck has no issue handling the weight, at 33' the wind likes to wreak havoc, with power tongue jack hitching/unhitching takes but a minute or so. Don't know anything about Propride, but most WD/SC hitches are not overly tasking to install, plenty of vids online if you want to tackle installing the hitch that is available.
