Thanks for taking time to provide suggestions Craig, Thom, and Paul! The battery on our Tacoma is lead acid, so no LiFePo anywhere in the system.

Seems like the next step is to determine whether my Tacoma has a smart alternator. Based on what I've read on how a smart alternator generates current, I'm inclined to think not based on the duration and consistency of current flowing during my last test when the battery separator was working. Not 100% on this however.

Related tangent - a member on here has a like new/uninstalled ACR for sale. Might that not be a good test if not solution? Or, would I be wasting my time and money?

If you don't have a Smart Alternator and the price is agreeable then I'd jump on it. Even if only a single Sensing version, it still will be better than what you have.

A brief follow up in case someone runs into this again. In addition to working intermittently, I also experienced the battery separator "short cycling" while trying to diagnose this issue. Not good before a long trip with a brand new battery!

So, I called the mechanic we infrequently deal with and the Toyota dealership regarding the 'smart alternator ' question. Couldn't get a follow up phone call. Bought a multimeter and figured it out on my own. A 2006 Tacoma does NOT have a smart alternator.

Swapped in a like new Blue Sea ACR. Checked all wiring connections, disassembled and polished the terminals at the 3 pin truck-camper connection, used a dab of dielectric grease in strategic locations, and the charging system is now consistently working as it should.

While not the forward thinking 'evolve towards future lithiium' upgrade I was considering, it was an inexpensive fix that took some time and ingenuity. Thanks to those that offered suggestions and input.
