$2400 before you driven the coach - not hardly. Here is our 2 cents:
1. Make sure tire pressure is right.
2. CHF
3. Stabilizer. Just a voice from experience. The stabilizer may pay some dividends for normal handling but the real dividends are to stabilization in the event of a blowout. Been there, done that, got the full color tee shirt. Take a look at our post on stabilizer.

If and only if the coach doesn't handle well enough, do other adders.
