I contact the friend/RV tech on Friday and he no longer has the grey tank. It was sold. Don't remember the size. He told me that if you have the dimensions of the tank then any good tank maker can make a tank for you. You need to also know where the outlet is located in the tank and what size it is. rockin'

I read about replacing the gray tank in the 33 Excel and I have a problem with mine, but since Peterson is out of business I can't find one this size. Where did you find yours and what were your dimensions. Thanks
