I am in the process of installing the plumbing. I was wondering what some of you guys have used for the holding tanks.

I originally had some HDPE tanks made -- the seams failed I now have galvanized steel tanks  with HDPE tops that are screwed and sealed in place. I wanted the largest tank possible for the space I had and could not find tanks that were already made to fit the space available. I carry over 150 gallons of fresh and have 120 gallons of gray and 30 of black give or take 10 or 20 gallons. My vents and drops all go through the tops and are connected with CT connectors so I can remove any part or all of the plumbing or tanks in the bay.

Others have used different methods and materials --- that is what makes this interesting.

Ask a hundred busnuts about tanks, just like asking them about some other subjects often discussed here, and you'll probably get a hundred different answers!   Or as Monty Python said "Would you like the five minute argument or the full half-hour?"

So saying, my preference is for rotationally-moulded (oops, molded) one-piece tanks made from thick food-grade polyethylene, with heavy-duty fittings spin-welded in place.   I'm lucky having Ronco Plastics just a few miles from here, so no exorbitant shipping charges for me.   I have two 110 gal fresh tanks, a 115 gal grey and a 65 gal poo tank.   So far so good.

We have 100 gallon fresh water and 100 gallon combined gray/black.  Our first RV had separate gray and black tanks.  When we got our first bus, it had combined gray/black with a gray water bypass.  I thought separate tanks was almost essential, but found that it really did not make any difference to me as long as there was a gray water bypass.  That's what we have on this bus too.  By the way, I like the plastic tanks.
