Re: Irwin 28 head help
I don't think you read my post because all the information your wondering about was in the title and post it's a 1972 Irwin 28. It has no toilet or holding tank. I just need to know the location of the holding tank the pipes for pump out and vent are pulled into the head. The only places that I can think of where the tank would be would be in the birth in the bow or in the cabinet in the head.
