Our rig isn't as long as Iggy's, so our space in the exact same location only allows for the double recliner. Our studio chair is positioned for travel behind the co-pilot seat, but we can position it wherever once we're parked. BTW...our double recliner looks exactly the same style, but ours is in black to match the driver and co-pilot seat.
I also changed out the backsplash in the kitchen from mirrors to a style that mimics the old style tin ceilings (hated the constant cleaning of water spots)
I installed a fireplace where none existed, however, because I was restricted in real estate, it's not as large as rigs where it was designed to have one from the start.
Changed the bathroom door to hinge from the opposite side. It now allows us to create privacy when opened, and actually makes it a ensuite to the bedroom.
Oh......and as any man would do....replaced the living room TV from 32" to 40" and installed a sound bar.
My Georgetown is now a "Limited Edition" and I installed the badge to state that.
I'm addicted to mods....and there's no cure short of buying another RV.
