Black Tank Standard Size - '63 Globetrotter?

[Sweneau]

Hi all,
Having a little trouble finding the replacement tank for my '63 GT. Wondering if others have had this situation also. PO made a horrible flange connection and even piped the tub drain into the side with an equally inappropriate connection. Found the source of my rear floor rot as the tank top had a huge chunk that had separated and was sitting in the pan. All that fluid splashing up against the floor! Eck!
Wondering if I simply provide R/O (rough opening) dimensions to tank supplier, tell them where to place the 3" flange connection for the toilet, 1-1/2" tub connection, and hope it lines up, or do I order kits for each and self install?

Old tank is an "Owens Products" from Ill., but can't find them online. May be too old? Tank is 15gal (filled it to be sure). I don't seem to find this size online.

Hope the photos help show the issue.

Sweneau, Are you aware of the fact that trailers of your vintaqe had a black tank that only had toilet connection? There was no plumbing for sink or shower connected to the black tank. As you are having to replace the black tank and damaged floor you may want to add a grey water tank and plumbing/valve so you can properly store and drain sink & shower water. Back in your trailers day the sink/shower water was drained to the ground. Can't do that these days, now you must use correct drain piping to a dump site or a blue boy to haul grey water to the dump facility. Ed

I have a 63GT and that does not look even close to the original tank in mine. There is only a black water tank and the valve is on the bottom.

yeah, dat ain't original...

[Sweneau]

Yeah, not the correct setup wrt grey water. Haven't figured out where to place a grey tank though. May just use a blue-boy tank or when at full hook-up site, use collector assembly to discharge grey into sewer.

Thank you

VTS sells gray tanks that fit under the floor and above the belly pan (4" depth match frame depth). I put one in my 55 FC.

Your tank looks like RR Crane of Dallas TX made it...

I used RR Crane tanks to add both black and gray to my '56. That was at least 30 years ago with no quality issues since. Last year though some road debris damaged the blank tank beyond repair and RR Crane still had the exact same tank. While these tanks have a mounting flange running around the edge that you can secure to the underside of your plywood floor with brass wood screws, I also added two chains per tank for extra support. The chains run inside heater hose (provides cushioning) and the end links bolt up to j-bolts that I hung from the frame members. Holes for the inlets and the vents need to be custom-located and drilled with hole saws by whoever installs - you've got your old tank to help with the locations needed. All other hook-up parts and supplies for draining and valving are available at any plumbing supply store and any good RV service & repair store. Good luck with the repairs/upgrades.
