I ride my 93 FLHS up onto the bed of the truck. 700 pounds of bike 200 pounds of me. under the half ton limit good to go. I did buy a set of ramps that has two side ramps that if it goes bad I can put my feet down. I do look for storm drains and other type depressions on the side of the road to put the rear wheels of the truck in so the height of the tailgate is lower to the ground. Saves on the wear and tear on my nerves. One time I had to move a BMW 1100 RT (big touring bike ) and said I can just ride it up into the truck.
Well that bike is more top heavey than an Harley dresser and about half way up the ramp I got it all wrong and ended up sideways in the bed of the truck with the bike on it's side with me under it. The dent in the wheel well is still there to remind me.
