birdbybird, I love the pics...those dogs live the good life, for sure.
Our rig looks much like yours, despite a different floorplan and mfgr.
We still use the original dinette and sofa/bed (same one Cheese just converted away from). We tend to leave the dinette table down and forming a bed/sofa. When we added the two Katrina dogs that were young, we had two soft/collapsible kennels taking up the dinette/bed space while en-route. We store them under the sofa (via outside storage) in case we may ever need to use a hotel due to RV problem on road.
We keep sofa and dinette cushions covered w/ sheets to help wear and tear from the woofers.
Your pics show how much room there is in our small rigs, and how flexible the space is.
