My wife & I purchased our 31DS in October 2011. Our first experience with coach was the return trip was home from Phoenix, AZ(where purchased) to NC. It was an excellent get "familiar and acclimated" trip. Our travel and drive experience with the unit was very pleasant and yielded no real surprises. As suggested the test drive is a definite must. Be sure to examine closely and have dealer repair any needed adjustments BEFORE you take delivery. Also, expect to find and look for any warranty issues after purchase. On our return trip we kept a punch list and added to it the issues(very minor stuff) we found. Once we arrived at home, we carried the coach and punch list to the closest Jayco dealer. They checked off our punch list and made the corrections.
We just returned from a trip to Charleston, SC where we towed our jeep. We didn't have any items added to our coach punch list. The "Cave" as we have named it, performed wonderfully. We could barely notice the toad.
I must say, I don't like the magadyne dvd, cd, radio, rear camera, nav combo unit. My main beef is that you can't use the rear camera to keep an eye on the toad and simultaneously enjoy some tunes. I wish there was a split screen or something. The options for us are to add another LCD screen for the camera or buy a combo unit that will meet our needs. We are currently in research phase.
Congratulations (albeit a tad premature) on your Greyhawk. It is proving to be a perfect fit for us. Can't wait for the next excursion!
Best of luck,
Kettrell & Sharon
