No personal experience, but I saw Jeff Franz using one (or something similar) on his Allegro Bus at Escapade. It really worked well for him. Jeff is not as heavy as I, so at 215, I'm not sure I would want to carry too much up one. I realize there is a safety factor in the 250# rating, but... On their website, some models are rated for 300# so I would be more comfortable with one of those.
