This van completely bailed us out. The rental we had originally booked broke a few days before we left. Orion and Kate's van completely saved our trip. We spent 9 nights in Grand Teton and Yellowstone. The van is a little dated but I think it adds to the charm of it. Mechanically the van ran very well. The power supply was more than adequate. We camped off grid the entire trip and I never saw the battery go lower than 85%. The fridge was huge and storage space was more than adequate. You do need to be plugged in to shore power to use the water heater but that was not a big deal for us. The only drawback we had was the water supply as it takes some effort to fill the 5 gallon tanks. I recently had shoulder surgery but it was still doable. Not having a shower was inconsequential as well because we just showered at the National Park campgrounds. The diesel heater was definitely one of the stars of the show as it got down to the 30's at night. I would definitely rent this unit again if we are ever up in that area.
