Has anyone tried charging their battery with a portable generator while driving down the road
If you're "driving down the road" then your alternator is spinning. So... if you want (need?) to charge while underway, why not just upgrade the wiring from your truck to TC so that you can charge effectively straight from the alternator?!? It's way cheaper, easier, and faster than than running a portable generator.
I have 2ga wiring from my truck's alternator straight to my house battery bank. I can easily charge at over 100A (@14.7V) when the battery is discharged... and power my fridge to boot (note that I do have a high-output alternator).
