I don't know if our 2007 Discovery is considered old, but every year we go look at higher end coaches and come back to ours with full slide and realize we have a great floor plan that suits our needs without spending a pile of money. One of the best upgrade we did was getting rid of the Norcold and replaced it with a Samsung residential refrigerator along with a 2812 magnum inverter. Don't have a picture handy right now,but it still looks great as I keep it polished, and do a good time consuming polish job on the wheels. Not bragging but spending a pile of money to upgrade is not in the cards for us at this time.
