I also have a 2015 Ventana on order, I picked out the 4369 floor plan. Just so you have something to compare against, I was able to negotiate down to 26% off msrp of the coach and all the add ons. I live in Denver Colorado and was fortunate enough to find a fantastic salesman that helped me tremendously in choosing what I ultimately ordered. This being my first rv, though I've owned toy haulers / campers in the past, he was instrumental. Even though he had several Ventana's for sale on the lot, his main concern was putting me in the right one. I ended up special ordering exactly what I was looking for. He was very knowledgeable and a RV'er himself, so he was able to explain the pros and cons of the different floor plans and options. Thats what you are looking for in a sales guy.
If you are interested in speaking with the guy I dealt with, send me a PM. Good luck to you.
