I've seen the front hitch carrying bicycles and even some 50CC and 100CC bikes, which were lighter than your bike, and thought it was a great idea. Less bounce than the RV back mount, I think, and more bugs but it would really depend on just a few issues that would need to be solved:
FGAW: Will the front hitch and bike at 310 lbs keep you within the front axle limits as well as the overall balance of the whole rig?
Headlights: Will the headlights be impaired? If so, one idea is to install extra plow lights that can shine over the bike or extra driving lights on the bumper.
Loading and unloading: I guess this is an issue whether front or back.
Post some pics of whatever you decide to do.
