Thanks for the lesson on modern small diesel trucks. As you can tell, my experience has been limited to larger semi tractor and diesel generator units, all 24 volt, and nothing modern at that.
I agree wholeheartedly on the limited benefit of dual batteries on a Spyder. As you said, all the second battery does is buy time if you exceed the charging system output. Police vehicles use two batteries, so they can run all the lights, radio, etc., for extended periods when idling. The benefits to a Spyder would be similar. Folks wanting to run a light show with accessory lighting for hours at a bike show with the Spyder not running, could gain something, as might people that ride in parades a lot...with extra electrical accessories. Other owners are not likely to do anything but add to the complexity of their Spyders, and spend some extra money.
We used to run duals. No longer. Most crown vics and Tahoes simply have a huge alternator now. Almost no bulbs anymore either... Light bars are LED, and laptops replaced the heavy MDTs by motorola. Times have definitely changed
