If the ramp on the 21 is anything like the ramp on our 19, you'll probably want to lessen the angle from ramp to trailer.
Speaking from experience of losing that $11.00 jiffy-leg spring on the bagger when I did not heed the advice of forumers who advised same to ol Sportster. DOH! Bottom line, when loading the scoot, jack the front up as much as you can and put a couple of wheel chocks under the back of the ramp. Bridge it w/ a 2x12 or a short ramp of some sort. That way ya won't drag goin in to the trailer.
Outside of that - enjoy the trailer and the scenery!
...don't think of it as work, just try and enjoy the game
