We used to load all our sleds in pickups in da UP. to unload it, all you have to do is pull the sled back until the rear drops to the ground then drive the truck forward (you usually need to go park anyway). You can drive forward carefully and the sled will simply drop off the tailgate easily as the skis clear. I have used all sorts of banks when snow is low. It is usually best to find a bank that is sllightly higher than your truck. Drive the sled up on the bank, and then back your truck up to it. That way if the sled doesn't go right where you want it to, you can make another pass (or 2 if needed). Then you can almost idle down into the truck bed.
I have also gone through a 2-place and into the truck using the trailer ramp. Like Dave above, this used to be how I took 3 sleds with only a 2 place trailer. The whole key is to do it calmly without any violent moves. That is how things get broken and YouTube gets populated with more funny videos.
