We are in a 2023 382RK. We have terrible odor under the kitchen sink when we are not on full hook ups. We do not have the vent under the sink because it’s vented directly out the side. When I run water in the kitchen sink, the odor will knock you off your feet. Doesn’t matter if it’s hot or cold water. We aren’t new to rving and we’ve dealt with odors before but this one has us stumped. Again this is only when we are not on full hook ups (no sewer). Any suggestions would be greatly appreciated
