Thanks everyone for your responses. Excellent information and some things to consider.
The underlying theme amongst all the responses is to look more closely at Newmar. I've went to their site and it appears the King Aire is the line that I should consider in equivalence to the Entegra.
I did consider the specs for the chassis and the Spartan won me over in part because of the box design. The Entegra was my first choice because of the build quality as well and the voluminous space in the basement.
Most if not all of you seemed to throw Thor under the proverbial bus (pun intended) but I didn't see any reasons why. I suspect that part of this has little to do with the chassis discussion but perhaps overall build quality, warranty, maintenance or some other issues. I was on the fence with Thor anyway so it's not a big deal to me. I was just hoping I could have gotten similar quality and saved some paper too.
Anyway, thanks to all of you for your comments. I just built a Newmar King Aire online and then I'll compare it to the Entegra Anthem.
