That has, to me, a major advantage: Unless I've got that tank's independent pump selected, I KNOW there's fuel in it up to the between-tanks pipe. With Aux selected, I can run the system "dry" down to the pickup tube in the Aux, because any gas the TB doesn't accept, goes right back to that tank.

Ken,
If by the drain for the auxiliary tank, you mean the plug in the bottom I might caution some about that. I will admit that I know my coach went to Mexico with the prior owners, but I can see strike damage to both tanks and the transmission pan. None are huge, but they also aren't a pipe elbow sticking down another inch plus.
I do have a suggestion. If you are working on the fuel plumbing and choose to to the High T Mod (That makes fueling go so much easier), it would be simple to place a T in the fill vent line to the auxiliary tank and be done right there.
We use a different and so far very successful fuel management plan. We run on the main tank until the indicator says about half, then we change to the auxiliary tank. This has two values. First, it means we are burning off the old fuel that might still be in the auxiliary tank. Second, we will still have the bottom half that we can use some of the run the generator if we need to. So far, this has worked out well. I also have to include that I replaced both sending units a few years back and they are both still working as hoped.
