Glad to hear of your good experience, Steve.
My experience was also positive, despite the troubles I described with the surge protector. The test of an organization is how they respond when something goes wrong. As I said, I'm very happy with the way everyone at Phoenix responded to my problems. I'm now in an unremarkable RV park near Amarillo, TX, with over 3000 miles on the 2552's odometer. I finally found somewhere warm enough to test the air conditioner. It works great, as does everythng else, now, on the coach.
I agree with you about the Pioneer stereo and nav system. It sounds great, but is best operated by a passenger, ideally a passenger with high tolerance for user-hostile devices. But I knew that when I ordered it, so I can't complain.
