17Z has been great for us! We have 2 small kids, started in 2010 when they were 2 yrs old. Camper has been great, no warranty issues, nothing to gripe about. There are lots of 17Z owners on this forum that will say the same. It's a great floorplan in a small unit. Regarding the price, get a quote from RV Direct and bring it to your dealer and see if they will get close. If I had the storage room and the $ I would have got the 19H but no regrets so far.
