As a rver, I always notice rvs on the road. Most are "run of the mill" factory built units. When I see an unsual rv I take special notice.
I met Mel from Peoria, Il. at a rest area and struck up a conversation with him (image that!). He and his wife were headed to "the valley" in Texas for the winter. They spend their winters in the Brownville area and their summers at home in Peoria.
Their rv is a conversion on a 1962 GMC Greyhound bus. Not one of the "high dollar" factory rigs but an owner built unit with all the comforts of home. It was already converted when they purchased it 7 years ago but has been remodeled by Mel to better suit their needs.
The bus has apartment size appliances instead of the usual rv size units. Their Danby refrigerator (very energy efficient) runs off an inverter powered by six 6 volt golf car batteries when on the road and the inverter switches to a battery charger when hooked to shore power (regular electricity from a light pole) or plugged into their onboard generator.
I would have visited longer but I had over 400 miles to cover before my day could end.
