Washer Dryer fit
Hmmm. Well I don’t have a solution upfront but we own a 2002 HR Admiral SE, 36 feet on a W22 chassis. Our bedroom door (a pocket door) is wider, unsure because it’s in storage, about how much wider, so it doesn’t sound like the same unit.
Our washer/dryer space ( for a single combo unit), is located in the kitchen area just left and down from the fridge in the floor cabinet.
You must have a DP with a different floor plan maybe?
I’m hardly an expert as we have owned ours less than two years but 19 inches seems unsafe for a bedroom door and too small to be a door for a WD. Could the rough in be in the kitchen?
