Ready to purchase, I think

After months of research and emails back and forth to my closest dealer, 5 hours away, I am now ready to make the plunge. I will be traveling to Salt Lake this weekend, pulling my Coleman pop up in exchange for my new 2009 2720 (and a lot of $$). I still have a few reservations regarding pending purchase, mostly because I have never seen a TM up close, so I am relying on this great forum and brochures.
1- with my dealer 5 hours away, I'm a little nervous about any warranty work or potential issues with the TM. Are there any known issues I should be aware of and make sure I check out before I pull off the lot?
2- Compared to my "pop-up", is the setup and take down of the TM that much faster and easier?
3- I don't know if you can help me with this one, but can you think of any advantage of purchasing the TM this fall compared to next Spring? Do you see the prices of TM change much from Fall to Spring?
thanks and I apologize for the lengthy message.
