Your best bet probably to get an alternator DC-DC charger like Ecoflow or Bluetti That can have up to 800W (with the engine running) to charge your Jackery (if it can take it.)
I have Fumoto valves on every cars/trucks/motorcycles I own right after the 1st oil change for the last 40 years... Highly recommended! Just flip the lever and drain the oil without even get a single drop on my hand.
I really doubt that the transmission 'learns' anything. What does it try to learn? Shifting is based on rpm/speed. What if the truck is shared by 2 people everyday like husband and wife? Is it going to learn and relearn from each driver overwriting one another? I really doubt it but of...
I'm not sure what the transmission is trying to learn? The only difference between each driver is how hard he/she steps on the gas. Isn't transmission shifting based just on speed? Then why does it matter how I or my grandma drives?
