Looking for our first used Diesel Pusher

Just hang out on these forums and you'll learn most of what you need to know. I've been looking at DP's, too, and talk to owners, read the forums, and look at used one's at the various dealers. I've learned that Tiffin has some excellent customer service from the factory no matter how old your rig is and builds an excellent RV. Newmar is also an excellent builder. You'll learn about the various chassis, rear radiators, side radiators. Seems that quality comes with price.
