Don't let concerns over backing up dictate your choice. It took me 2 hours to back into my driveway the first time with a 25' TT. Now I can set it right back in there in one motion. Longer TT's are easier to back anyway - so its been said on here. I believe it.
Our current floor plan is becoming uncomfortable for us. We don't have good space to hang out when we need to. So consider that and get the floor plan that allows you to be comfortable. Envision where you would sit and watch TV if it was raining outside or if you like watching before bed after a shower. The dinette won't cut it - trust me.
Good luck!
