1958 deluxe black water tank

RONCO PLASTICS, is located in Tustin, CA  (Redhill and Edinger) They have a crappy website, but great products.  They have been making custom plastic tanks for the past 45 years at this same location.  They make the tanks by the sizes they show, then they offer various wall thickness, and then fresh or black holding.  Lots of options.  I picked up a tank this week and will return next week to have my fittings installed based on my marked locations.  This is a big company, they ship hundreds of tanks per day.  I buy a couple of tanks from them each year.

They run on a 7 to 10 day lead time, and are reasonably priced.  I think product shipping cost is the killer, but they are local to me.

I never buy their "heavy duty" tanks for my trailers.  I think they are made for marine, or off road applications which see extreme vibrations.

You need to pick out one of their existing sizes/shapes.  Then send them a diagram of exactly where you want the bungs spun welded into the tank.  I think the only hard part is communicating exactly where you want the locations, which is why you would want to send a diagram, not make it a verbal purchase.

Spin welding the plastic bungs is easy, but you need a special mandrel.  It's not worth buying a special mandrel (you need one for every fitting size) unless you are doing this on a regular basis.
