I like bunny hopping stuff, but it's a drag that you can't do it with much of any load one a bike...
It is harder, but not impossible with a loaded bike. At the very least you can manage to take most of the impact off even with a heavy load. I have managed to hop stuff even with a fully loaded bike. It is one of those skills that I am better at when I actually need it and don't have time to think about it than when I am doing it for the fun of it.
