dune buggie.? golf cart. it will work, ive seen some of the pb tanks. but its your idea. heavy duty garden cart. works ok behind my yam warrior. but i dont transport people, just bricks.
i dont advise you guys pullin a cart behind an atv, fear of flip over, but thats just me, its not worth a few people heading to the hospital because of somethin dumb.
all I ask is everyone to have fun and not get messed up.
