This like the 2nd time I've seen "Destination RV"
IS that like a park model. NO fresh tank. No waste tank Designed to be put on a site and left there? If so then it's designed to always be plugged in and from a "House" standpoint needs not have a battery.
Now from a Towing standpoint... Depending on the weight it may not need aux brakes (Trailer brakes) or it might have a surge brake system that also does not need electrical power... IF it has electric brakes.. then it needs an emergency brake battery.. but only if it has electric brakes.
