You going to weld some plates to the sides to strengthen that weld area? It will be weaker than the original frame if you just butt weld it together. Another piece of channel facing the weld would be even better. Also welding along a diagonal helps.

Well after all of that, the tanks just arrived, and the drain fittings are already installed! (they were supposed to be blanks, that's good I think I ordered the wrong ones from VTS)
I just need to decide how to attach them...They are supposed to just be screwed up thru the subfloor (with stringers I hope)I'm not sure I'll do that I may fabricate some bolt- in flanges.
If anyone is interested....I looked today on ebay today and a supplier has just listed a very similar sized abs tank 50x22 3/4x 8 and it is $60 cheaper with free shipping! $159= should fit between the rails
These hang below the frame a bit you will have to add some metal and new skins.
I had a sheetmetal shop brake me up some channel.

Yes, I'm going to 1/4" plate the joint, plus I'm welding an extra 4" channel underneath that from the axle mount plating(with some plating there too) back to the bumper to help with the rear end sag issues and accomodate the tanks.

I just used black ABS glue when I put my new fresh water tank in my Avion. It has held fine for 2 years now.

Is that a "black plastic" abs water tank? The glue I found is medium bodied abs- it is black.

Yes it is a black ABS water tank. It is made up of 1/4" sheets of black ABS, glued together, with moulded ends. I drilled the hole for the fitting, which had a flat flange on it for the glue. And used black ABS pipe glue.
