1. Slide
2. Replaced crappy mattress
3. Ventilation from all 4 sides.
We have 1 and 2. Since we went from the hybrid to the current TT, we now only have ventilation (windows) on 2 sides - really miss being able to get the breeze from any angle.
Not sure if the one that said bathroom was no big deal meant no bathroom at all - I don't care about the SIZE of the bathroom, shower, etc. They are there, but it mainly just gets used for middle of night trips (which I sometimes still go to bath house so as not to wake others).
