What Ron said is largely true. For years I thought my MH rode good because of the added Steer Safe that is suppose to keep the tires running straight. This is a $500 mod if you do it yourself. The MH had it on when I bought it so I just believed it helped. I drove home from OH to CT without it because of an accident and felt no difference in the handling of the MH. I still drove it with one hand even with passing trucks. I think weight distribution, tires being balanced, tires not out of round, a good front end alignment, and learning to drive the MH will be your cheapest mods.
