Is it hot in the Bedroom?

We are looking into purchasing a small RV like the TM and reading all the forums to educate ourselves on them. My question is, Is the "bedroom area" where the mattress is located tend to get hot in warm weather? It doesn't seem to have any air flow except for the window above the bed and I was wondering if there are any a/c vents or fans in this area? I'm in that menopause phase and need the air...ha

Also, besides the toliet, is there any other "differences" between the TM and a fifth wheel (which we have now) besides the size and that the TM folds down and the gas mileage? We really want something smaller and a unit that is easier to park, but dont' want to give up on all the comforts.

Thanks so much for the info.
