it really does depend on the truck/trailer combo. For my F150 Off Road I have two 2" drawbars, one 3" drop, one 4" drop, and a pintle/2 5/16" combo with no drop. Depending on the trailer's tounge weight and hight I switch. Rarely do I use the same one twice in a row. I followed Uhaul's advice about the 18" rule and it was a waste of money. I needed to have mine higher than that. But leveling the trailer was very important, as I was hauling livestock.

Light as feather and rated at 13,000lbs with a 2000lb tougne load... This site says 1300lb tougne. It says 2000lbs on the 2" drop 1" shaft size I bought.. Whats nice is you don't need to grease them. No rust, no mess if you want to put it in the truck...
