You are renting it, so go with the floor plan you like the best. A lot of your questions will be answered and it will have been your "best guess" not someone's opinion.
If you like it fine, if you sort of liked it okay, if it just did not work out as planned, oh well, you are going to give it back anyway.
Floor plan remain, when all else is accepted of forgotten.
My 25 ft. TT did just fine in the 90 degree plus heat this week end. We were in the shade and the AC it kept the TT in the upper 70's. I would not have wanted to test it in direct sun. We were outside in the heat and humidity most of the day, so sleeping in a cool TT at nice was a real treat.
Good Luck
