Yeah I was also think of putting it on a wheel system and be able to push it. I know they weight is about 500lbs but if I could build something to put it on and pull it out when needed. I could store it in the trailer. Just not sure if that could workI thought of that last night,was going to post it today. You should be able to get a front receiver hitch for your truck.
You could put the leaf loader on a wooden base,or metal if you can weld, and put a scissor jack on each side to lift it onto position, and put casters on it so you can just roll it away.
There are obviously downsides to this,
It's a long tube,high in the air,hard to reach, and it will plug up.
