I looked at a 4103 before I got my '04. It was a nice bus but much more cramped than an '04. The one I saw had a sunken alley down the center so there was no head room off the aisle. Had a nice sounding 671 in it, but really it rode like a garbage truck. My feeling on springs is that when you get the right load on them they can have a really nice ride, but when they don't there is nothing worse. When my band used to run a schoolie it was horrible empty, but when we filled it with PA and gear and people it was a nice civilized ride. Just had a thought, maybe water ballast.....I should get back to work
