This Ram Promaster was converted to an RV who is a cat lover. We installed a 13500 BTU AC, Maxx Air roof vent, swivel seats, WiFi & Cell Boosters, running boards, and awning. It is powered by 2000 Watt pure sine wave inverter system with 80 amp charger 4 AGM batteries, 30 amp shore power and 200 watt solar flex system. We created a full kitchen w/full pressure water, hot water fresh, gray tanks and a shower with porcelain toilet and black tank. Besides the large platform bed, we created a jump seat that also makes a bed. You'll see some custom items for the kitty cat like the open area under bed. We installed 2 conventional slide windows, night shades and matching privacy curtain.
