I'll jump in with my opinion.... Back in 2004 (before we purchased our 1st MH) we rented a 31 ft. Fleetwood Tioga class C and it had a somewhat similar floor plan to the Forza in that all the seating is on one side.
If you have friends/family with you, it's like birds sitting on a fence, everyone is on the same side. You DO have the passenger seat that turns around but just one spot across from all the other seating.
So, I vote for the Tiffin as it has more balanced seating. In the Forza, I'm wondering if the bathroom door will hinder your entrance into the bathroom while the slide is closed, the Tiffin appears to have a sliding bathroom door.
I know you like the 'mid door' but the front door allows the slide to start earlier in the sidewall giving you more openness in the living area.
Another deciding factor is where the 'factory' is located. I see that you are in Florida and Red Bay, AL, is closer than Indiana.
Whatever you choose, you will have fun!
On edit: Check the CCC as the Tiffin with 4 slides is going to be close to max weight.
Safe travels,
