Thanks Wayne. I certainly agree that aluminum is not the best choice for a holding tank - especially a black one. Based on the fact that this tank has taken a beating I would suspect a PO got tired of the plastic one being ripped out. The drain system was an abberation also and had been ripped off by a tow company when my previous owner had to be towed. All the broken pieces were just thrown in the coach when I got it - but the aluminun tank was intact. I have actually replumbed the drain system since I took the photo showing the tank installed. I figured out a way to use 3 inch pipe rather than the 4 and 5 inch stuff that was on it. I added a macerator and installed a flexible elbow with the thought that it would provide a little flex and maybe keep me from tearing the drain system off.

Is it possible for you to give me the capacity and dimensions of the tank on your coach? A photo would help also, if you have one. That information would help me determine which tank I need to search for. I talked to a couple of the companies that provide GMC tanks but could not really determine which size tank to get since my only point of reference was the aluminum tank. It is only about a 16 gallon tank and I want a larger one.

Thanks again for your response.

Thanks Mr. Hamilton. Do you know if this is the same size tank and configuration as the original tank? I guess I need to call Jim K. and discuss this tank as a replacement for mine. It doesn't really have the capacity I was looking for but there is not a lot of room in that bay for anything much larger.

Wow! I don't know what I did to get a message like this from you Mr. Kanomata - especially on a public forum. It seems you are trying to make some sort of point at my expense. It would have been more appropriate for you to call me since you have my phone number. I just spoke to you this week on the phone and ordered a Dino board and oil filter seal for my Onan so I know you speak English.

I tried to participate in this forum once before, and just started posting again a few days ago, but it looks like that was a mistake. I thought the forum was established to provide information and help to ALL GMC owners. I admit that I am not very knowledgeable about the GMC and can't contribute much to help anyone at this time but had hoped, as time went by, I would be able to help someone along the way.

With all due respect to your knowledge of the GMC, and the service you provide, it sounds like you think we just "rattle off" and we are to just "listen" to you and do everything you say. I would think that most customers would just hang up - I know I would - if you told them to "shut up".

By the way, you didn't send me an e-mail regarding my order as you promised you would.
