Looking at all the pictures from you and other places, its not a diesel pusher. The engine is in the front so you may get more noise, would have to drive to see.
I downsized from a 35ft 5th wheel to a 29.3 ACE. After two years in the ACE we decided that we downsized to much. I had no real complaints about the ACE the V10 work far better than I thought. The interior quality of the ACE was not there but then I knew that going into.
You may want to rethink the only one AC and 30amp. My ACE had only one 15000 and it work hard to keep the unit cool. With 30 amp its hard to add another AC.
Good Luck and enjoy
