70-75 fresh water tanks are not the same

[CaCraig]

Vintage Trailer has the same tank listed for 70-75. Yes they say it fits many but it doesn't fit my '71.

My original tank is a 'H' shape and the ones at Vintage (probably others if the come from Inca) is an 'H' bit it has another part coming out from the middle where it goes over the frame. You can see it on Vintage's website. I went to Inca to pick my new tank up.

The problem is, that protrusion makes the inlet about 1.5 inches further from the midline of the tank, and right below the partition for the galley cabinets. Now I can't get the inlet to line up with the tank.

I've tried all sorts of pipe fittings and it won't work.

So FYI, check your tank before ordering.
