I have an 08 33sk
1. It came with a 26" flat panel LCD tv with a wall mount. There is room for a arger tv.
2. If the tv is an older tv, it may not set on the counter. There would be no problem with a flat panel.
3. I'm 6' and have no problem. The toilet is on an angle and that helps with leg room.
4. If you had no problems with your other unit backing, you should not have problems with the 33sk.
I have only had mine in 1 pull through site. I went from a 27' TT to the 33sk, 8' difference in length. I have had an easier time putting the 5er on sites that that were hard to get the TT on.
5. The microwave in the 5er is bigger than the one in my house, so I can't really answer that. It is not that much of a concern to us, as we hardly ever use it for anything other than heating water for tea.
6. This one, I won't answer. My unit is unique, it was built on a Friday before a holiday.
I would recommend getting the insulated windows and insulation upgrade.
