Dad built one years ago that had a permanetly mounted old style tall bumper jack [from back when cars actually had bumpers and they were chrome] mounted to both halves. After pulling the lock pin he would just jack the tilt up. Cheaper than winch or hydraulics. It worked very well.
When he built it, he never thought about a tilt trailer being only good for one item. The trailer was large enough to haul two garden tractors. If you have two items to load and pull the first one on the trailer then you can't tilt it to load the second. Thats where the jack came in - it held the trailer deck tilted until he was done loading. Then he just put the jack in the down mode and jacked it down.
Wish I had a picture.
The trailer pictured above wouldn't stay tilted on its own without some sort of holding mechanism because there is more "bed" in front of the axle than there is in back. Regular tilt trailers have more behind the axle so gravity holds them tilted when empty - and unlocked. With one of those even if you use ramps to load two items they become tail heavy real quick and will not pull straight. With the one pictured above that wouildn't be a factor. The trailer pictured above is a very good setup!
