Standard hitches are rated Class I/1 (maybe a light-weight bike rack) through Class V/5 (some 3/4 ton trucks and nearly all 1-ton and heavier). You don't say what year your F-350 is... mine is a 2012 and is rated for 1,750 tongue weight with a WD hitch and 850 without WD (not using the 2" sleeve adapter). Yours seems pretty standard. As stated by others, I can't imagine why one would not want to use a weight-distributing hitch with anything heavier than a pop-up or lawn trailer. We used one when we had a travel trailer and, besides leveling the vehicles, it provided excellent anti-sway.
