When I moved from VA to FL I had my bike in the back of a Uhaul with the rest of my stuff. Bigger truck, 17 foot or something. Had the wood slats that were raised off of the metal wall of the truck. I just took my tiedowns and looped one end through the little gap, hooking it onto itself. The other end of the tiedowns were attached to the bike's frame. One strap on each corner of the bike. Straps were used to keep the bike from swaying side to side. Left it in gear to prevent rolling back and forth with stuff jammed against the tires to help reduce front to back motion. Also, covered the bike in blankets to prevent an oopsy.
Like slowrat, side stand is always down when I trailer a bike, even if if doesn't touch the ground.
Zero problems. And you should see the way I drive. Even in a Uhaul.
