I'm a day late & a dollar short on this but I vote for the trailer. Rent or buy you won't be sorry. You can load the bike ,parts,& just all kinds of stuff. A flat tire on a trailer, if you should happen to have one, won't be near as bad as one on your car. Just be sure to get the anti-sway bar & load levelers, safety chain, crisscrossed(X) when connected good light connections & hitch. You can fabricated a gravel shield from plywood. I own a tandem axle & installed a semi-truck windscreen on the front & it works great. Might check some of your buddys to rent one from them a bit more reasonable. Oh be sure to pack the wheel bearings & check the tire pressure often like ever time you stop for a rest or fuel.
Best of luck on the move. When we moved to Ore. I made 8 trips with mine hauling my junkers. I did this in the middle of winter (1200 mile) roundtrip over icy roads & snowy mountains. Never had a problem.
