I'm one of those that own a "pig with lipstick"... I've had far fewer problems with my '14 Tuscany 40RX than I've ever had from any RV that I've owned from popups, bumper pulls to 5th wheels. Thor had some transition problems from Damon to Thor, but, mine at any rate is worth every penny I paid for it. Freightliner XCR chassis with 60 degree turn, 450 HP/1250 torque Cummins ISL...every option in the book for that year. Granted, I'm not familiar with XTE version, but, I'll keep my 40RX and I'd do it over if I had to.
As far as discount? A lot depends on the dealer. Some dealers will balk at much of a discount on the newest models on the lot, and 16's are just that. They haven't sat long enough for the dealer to want to turn them over and they are thinking that some folks will pay a premium to own a '16 since 2015 is barely half over. Other dealers will take a deal just to move those expensive coaches. If it is what you want, make your best offer...the worst they can do is say "no" and they may come back with a counter offer that is close and still something that you can live with. The important thing is to keep your head and walk away if you can't get a price that has "value" to you and "value to you" can't be stated as a black and white percentage. Whether it be a Tuscany or any other brand. A "perfect match" in floor plan and features is surely worth a few more bucks than driving a "hard bargain" on something that is lacking in that "perfect coach".
