Yes, that seems reasonable.
Since modern light-duty vehicles don't have any chassis parts which require greasing as part of maintenance, "chassis grease" is no longer a very familiar idea for most people (but then, their wheel bearings don't need re-greasing, either).
for chassis (LA,LB) and wheel bearing (GA,GB,GC) applications are different, but the same product is routinely sold for both purposes (e.g. MotoMaster Wheel Bearing and Chassis Grease
, "meets the NLGI Service Classification category GC-LB").
You can buy nice synthetic grease which is probably quite suitable in a convenient small tube (e.g. Permatex Ultra Slick Multi-Purpose Synthetic Grease, 85 g
), just like the white lithium grease, if you don't want to pump a bit out of a gun (which I find awkward). If you are using a gun to push grease into the E-Z Lube fitting of the wheel bearings, then yes, I would put the same grease into the hitch's zerk fitting. If you want to be sure, look for NLGI Service Classification category LB on the grease container.
