If QB...
I used a 26' Uhaul, which was way too big, but the per day cost is the same and I wasn't worried about space.
If you're going quickbuild, and picking up directly from Van's you can still transport in a van/truck/lorry a la Partain, and have it quite manageable from a load / unload perspective, if you don't crate it (also saving, by the way, $500 in crating charges).
The trick is securing it so that it isn't damaged. If you call Van's, someone in their shipping department can explain how they pack them (my source). When I picked up my QB from Partain (having driven across the border myself), this is what we did...
Wing strapped to each wall, with cargo straps, and tie off the spar to the wall so that it can't slide fore or aft. Use lots of furniture blankets to protect from rubbing on the wall, straps, etc. Of course, the inside of the van will have to have good and appropriate tie spots (I rented a Uhaul).
Fuse was easy. First, fold the 4 loose skins (QB) in blankets, and set them in the center (width) of the floor near the front of the truck box. Put the cardboard box with parts on top of the blanketed skins. Then load the fuse, tail first, so that the tailcone rests on the box and the center section of the fuse just rests on furniture pads. Use more folded furniture pads on top of the box under the tailcone to prop up the tail until the center section sits flat, then tie off both ends of the fuse to all four corners of the box to keep it from sliding around. A bunch of other stuff (wing tips, etc.) stay packed in the fuse itself.
I didn't get my finish kit when I picked up my QB, but have had it recommended to have four folks to lift/load the crate it comes in. I don't know if you could unpack it to load more easily or not. We loaded/unloaded the wings and fuse with three, and I wouldn't want to do it with two (can unload with two, but holding the wings to the wall while you strap it really requires three).
I don't know how far across the border you have to go to get to Van's, but if you want to shorten your trip, you can get Partain to haul it to the border for you, and then just zip across to trans-load it and bring it home. That worked well for me, and Partain gave excellent service. Don't forget to factor in the cost of fuel in your rented truck. I'm not sure what engine the one I used had, but I'm not sure it needed a radiator because it seemed to be 'gas cooled'.
Good luck.
