As a current owner of 2 Thor MH's and someone who has looked and shopped the 33.3 I will offer what info I can. First, Thor is hands down one of the best companies I have ever dealt with. They truly support their product. I love Thor as a company. Thor has a knack for being innovative (mud rooms, electric bunks, laptop desks) etc and seem to be the first to incorporate "neat" and functional ideas from higher end units into trickle down versions. And in doing so are usually about the most competitively priced in any class. They are masters at getting more bang for your buck. The downside to hit this price point is usually found in the fit and finish. Not bad mind you but not high end. Quality is on par with any other offerings in a comparative class but fit and finish does seem to be where the price point is reflected the most. All that said to me equals value value value. Pair that with support and it's a winner for me and I will continue to buy Thor products. I have been looking hard at the 33.3. It's really hard to beat a cummins ISB DP on an air ride Freightliner chassis with a bunkhouse, Sikkens full body paint, low profile design, solid surface tops, real wood cabinets, 22.5" wheels, auto start gen with 2k watt inverter, residential refer, etc the list goes on and on for the price. From dealers to owners I have gotten feedback and they report the ride to be super smooth and very high end with little to no road noise. I have seen them on lots and approached owners at Cg's. One was about 2 weeks ago who had theirs 6 months with no problems and loved it and are happy to have made the purchase. One of the biggest selling points for me is that the power to weight ratio puts this coach in a position to boast 12-15 mpg. Some say hogwash but I can tell you some owners I talked to at length about their 36.1 (bigger and heavier than the 33.3) said they had calculated MPG at 12 and that was pulling a suv toad though the mountains. Most claim 12mpg is about right. That's a huge deal for me. I only have 2 real peeves so far with the Palazzo 33.3. One is the TPO roof over fiberglass. Not a huge deal and each has their merits but a solid roof would leave this coach with nothing to want for. Second is TV placement. The outside TV is fine, but the living room and to a lesser extent the bedroom TV mounts feel out of place. They sort of have that "well we had to put it somewhere" feel. It's not horrible but looks afterthought as opposed to integrated if that makes sense. Neither is a deal breaker for me, but it is a critique for me personally. Not sure where you are landing on price quotes but PM me and I can tell you best prices from a few dealers here in the North east. That said the 139k price is about lean as you'll get from what I am seeing. Mind you, you can get that same price on new 2014 with different paint options but the wait time now I am told is about 8-12 weeks. My local dealer has one coming in, I might convince DW to grab it. Love the 33.3. Good luck with your search and feel free to PM for any detailed questions.
