Last RV show we attended had many TTs/5ers where the sofa, recliners, or theater seating was directly across from the tv. Of those many had swivel mounts so they could be viewed from galley or dining sets as well.
Just keep looking, whether at local dealer/rv shows or on-line at manufacturer websites or sites like RvTrader.com for photos and videos of RV interiors from virtually every brand currently in production.
Our TT is older and had a tube tv installed in a cabinet, a few years back we removed and installed a HDTV on an articulating arm making viewing angle suitable from about anywhere in our rig. Enjoy your new TT!
