We just bought a 2007 model 4230, our first motorhome. So far we really like it.
One word of caution: Watch out for the automatic step, it's really low! It's not a problem if all you're doing is driving on nicely paved, even roads. We were on the coast this weekend, and I dragged it as I was crossing Hwy 1 from one parking area to another. I'm pretty sure I'll be permanently removing that step, I don't like worrying about it.
Enjoy your trip and your RV.
