Where there's a will, there's a way. We take our RS everywhere we go, and we're full-timers, living in a 33' Montana tag-along. I drive an 03 Sierra Dura Max, crew/long bed, and the all-up weight is a little over 20,000 lbs. The Spyder gets winched into the pickup backwards, so that the rear tire hits the front of the bed, and coincidentally, the front tires hit the rear of the trucks wheel wells. I have to remove the rear fender, which has 1/4- 20 T-nuts underneath, so that I just step up and un-screw it, turn it 90 degrees and put one screw back in to hold it off the tire while transporting. The stock back rest comes off and so does the windshield, to make room under the cap. The tail-gate has been modified to make room for the Spyder's nose. Did it with aluminum diamond plate --- you'd have to be there!

It really looks pretty good.nojoke My three folding ramps go on the back of the trailer, BTW.
Takes up pretty close to an hour to load, or unload, total, but it's worth it. Usually don't do it two days in a row, but it happens, occasionally.
Also, the cap is hinged along the left bed rail, and I raise it up with an electric jack, so that it's open 90 degrees, and you can just climb up on the tail gate and step on.
If I ever get checked out on how to post pictures, I'll do it. Hard to explain without them. Point is, anything is doable. Like LT Camley always said, "The solution that works is always the right solution."
Then, if you have an extra $6800.00 or so, burning a hole in your pocket, you could order up an Idaho Tote, which has two swivelling wheels, and a whole lot of capacity. Just get yourself a nice set of folding aluminum ramps like mine, and you could just drive your Spyder right on there.
You'll get it done. Just keep on working at it. Good luck.
