Any opinions on the wisdom of converting my old 5th wheel 6/20 hog trailer into a snotrac trailer? I know I'd need to make a pair of "risers" to get the snotrac above the wheels since it's only 6 feet between them. I'm not sure how much structural stength is built into the sides so if I converted it into sort of a flatbed the gooseneck hitch wouldn't be strong enough?
