I look at it somewhat different. I figure the stock brakes on my E350 chassis are about maxed out handling a 26ft coach. Add a 4000 lb Liberty and the brakes are going to wear out a bunch faster. I'll spend the $3600 to set it up with a tow bar plus brake system just because I don't like pushing the envelope on my chassis. A safety margin is a good thing in these sue happy days in my book. Also, I know I'm legal in any state.
