I just took delivery of my '69 Overlander. PO started his renovation, then gave up and sold it. I had it towed from Kentucky to Idaho, got it yesterday, and today started my work, and boy is there gonna be work. After generally cleaning things up and taking inventory yesterday, today I decided to finish the bathroom demolition that PO started. After a few minutes I had to wonder exactly how the black water tank managed to make the trip from Kentucky, and why it isn't on the highway somewhere in Nebraska.
I'm not sure how this is supposed to be installed, but it looks to me like the tank pan is galvanized steel, and sits on two pieces of angle iron, front and rear, that span the rear frame bay. I don't know if that's how the factory built it, but that's how this one was built. The rear angle iron (closest to bumper) is entirely gone. The Thetford valve was resting on a piece of steel channel that the bottom of the hose locker was riveted to, and that piece of channel, was attached to nothing.
Here's a photo, not sure how visible the problem will be.
This evening I freed up that portion of the belly pan, and managed to pull the tank and tank pan. Discovered the piece of angle iron at teh front, was, at its worst point, approximately 1/2" high, and pure rust. I really don't know how the thing made it here.
If you've read this far perhaps you can help me answer these questions. The trailer frame is rusted but not too badly. POR-15 should stop the disease process. But how was the tank and tank pan originally hung? Was it on two pices of angle? If so, how can I attach some new angle to the frame? I don't weld, I don't want to tow this thing to a welder (I fought it into my back yard which is where I'll rehab it, it is very difficult to get in and out of the yard). How difficult would it be to drill holes and bolt in new material? Or would that weaken the structure too much?
Your assistance appreciated.
Oh, yeah, of what should a new tank pan be made? Steel is an excellent material but in this day of synthetics do I really need something that will just rust again? Or can I buy one somewhere?
