I had some help from them. One was ground floor, we used a 4 wheel flat cart to get it to the trailer, then tilted it up onto the bed and scooted it forward. The other one was up some stairways, luckily it had a large base that separated, making to upper, heavier unit at least a bit less bulky and more manageable. I strapped it onto the two wheel hand truck and we eased it down the steps
I did have some steel ramps along, but they're only about 3 feet long and made it too steep an incline.
All in all, it was a successful trip, and now i've got all kinds of new junk to play in ; )
