Thanks! It's actually a single rear tank, odd because it's a "Trailer Special". I would think dual tanks would've been standard equip. Definatelt doing a Z notch. While a butt weld in a diagonal is better than a vertical butt I want more radial strength. I've done a few frame stretches and notches so I think I can get through that part good enough. The Bed is my main concern. I'll get some pics up.
