It's used on full hook up sites. I've used a regulator. The first was on the hot water tank under the kitchen counter. A plastic compression type fitting came loose and flooded the lower portion of the camper. Lucky I was leaned a little and most water ran out under the living room slide. It's just depressing to pay for a mercades and get yugo quality and craftsmanship. I'm sure heartland at most would say bring it to the factory hundreds of miles away for who knows how long and still not stand behind it. The water lines and care of construction will the the first things I look for when I buy another. If they sold for $15,000 I'd understand cutting corners, but the sell for $55 and up! The cost of luxury cars! This is also the second power converter that has been taken out by the water leaks, I guess someone at the factory thought in the center of the water lines was the best place to install the power converter so it gets drowned with every leak.
