I have a 2010 19rd and did a LOT of research before buying. In fact, I had to look around quite a bit to find the original rd when it came time to purchase. Here are at least some of the differences that I found. Mine has 3 burner stove and oven, newer ones, just 2 burner stove and no oven, I think some of the newer ones have plastic sinks, mine is stainless, I have a cabinet above the bed, newer ones have a shelf, mine has jalousie style windows, new ones have sliders---this was the deal breaker for me, it had to have the jalousie style. Mine has drawers under dinette, not sure about newer ones, mine has ducted heat, forced air furnace, 30lb propane bottles, mine has an adjustable tv mount on wall as opposed to shelf. Mine has wide entry door with window glass in door. I actually watched them build the 19rd and looked at several at the factory and knew exactly what I wanted...when they started changing things, making it cheaper, I knew more than the dealers that I talked with trying to find a "real 19". I hope this is helpful info for you...ask away if you have more questions.
