I don't know guys and gals.. I'm thinking possible, now don't beat me up to bad here just hear me out he would do fine ALMOST the way you see it with some modifications.. I agree 100% that the windshield would have to be removed---so once it is off the spyder (4 bolts right?) Now comes 3 other concern's--- Strapping it in----Tailgate weight------Loading and un-loading..
Stapping it in---Not the book method however, why couldn't he put a strap on each of the front tires (on the back side) and hook the other end to the front of the bed tie downs that are provided? Then as for as the rear tire he could strap it using the same tie downs or Chalk it??
Tailgate---This would be somewhat of a concern for sure, BUT having said that I'm sure the cable can hold the weight, the problem could possible be in the hardware that holds the cables in place, I'd take a good look at that for sure, but again, I'm thinking it would be fine..
Loading and un-loading---Pain in the butt for sure and you would need to use a LOADING DOCK at a store,, not impossible to find, they are all over the place, one big enough to manuver around a bit as well..
I'm just saying folks.. I think with some very important STEPS it is possible, even when we haul our spyders on a trailer there are risks,, this method is just a bit more risker I know..
Remember don't BEAT ME UP to bad--I by no means plan on attempting this I have a trailer but this person is trailerless and sounds as though he's somewhat in the market for one but for now I'm just thinking yah maybe, Not giving the GREEN light, just my 2 cents worth.. There ya have it..

PS: By the way, how did you get it loaded and unloaded, you never did say?
