Wind can power an alternator while driving around, no?
An alternator can charge up a battery rather quickly?
I may be mistaken just thinking out loud.
I do not still have that generator LOL nor a bicycle!
I'm confused now.. lol The wind "could" charge the batteries but the Alt would be more efficient honestly. Answer further below...

You can't user a wind generator like this?
while going down the road I can see a turbine wheel spinning and charging, then at base camp solar takes over

"GenniPod Gen II was designed with the specification of providing approximately 4 amps of 12VDC power while flying at 75mph."
This tells me there is a minimal amount of speed needed. A Cessna 152 needs to be at an airspeed of like 68MPH to catch enough airflow under its wings to create lift. I think cruising speed is 110-120 with a top speed of what 125-130MPH. At slower than possible speeds I wouldn't get anything out of it and indeed at that point the solar could be active while in motion I suppose but the solar setup I have in mind; I haven't really done enough research on it for autonomy purposes (bad or poor weather conditions). So all in all I could forgo the Alt/PTO idea but it would be nice as a main or backup as would the solar configuration. Not looking really for the best case scenario more of less along the mindset of say someone who wants more than 1-2 ways to make fire (like 5 in mine) in their EDC or BOB.. lol

Why not add a second alternator under the hood?
Well here in lies other issues..
- In the truck, there is already a 3 battery setup using a dual battery charging system. I can use the crank battery separate from the two deep cycles. However, should I kill the cranking battery, I have a way at the flcik of a button to join all the batteries to start the vehicle again. That already includes a single pair of 1/0 wires running down a frame rail from the battery to the old spare tire carrier area where the two deep cycles are [will be] housed in a saddled lightweight aluminum IP67 water proof/dust proof box that bolts to the carrier itself, (gives me easy access to the batteries should I need it and makes best use of the space).
- The trailer will have another 2 Battery system - dual deep cycle 200ah batteries. (by my calculations, 12a [max in use would be 32a and never at once really] at 90* temps, with both batteries, should net me approx 29-31 hrs of use time before needing to be recharged; which at that point, solar will have kicked in obviously to recharge and top them off again).
- Running yet another 1/0 or 2/0 pair of cables the length of the truck, - PLUS the trailer and gap between, isn't something I really want to do, have room for, want hanging between a hitch and a trailer connection, and or shall I surprise everyone - afford $25 a ft for 2/0 two additional runs of [and run it in a conduit as well too?) cable! I could certainly find better things to do with that kind of cash. lol
- Also, after 2020-21 I will have hopefully met my scheduled agenda to be more than a spectator at the 2020 Expo West in Flagstaff and completed or at least be near completion of adding the 4BTa into the truck which means it will be needing to go offline for a few months. Thankfully we have other vehicles in the household to use. So designing a 2nd Alt system when even then Ideally I have access to creating a 300-380a Alt if need be.

BUT.... the PTO shaft idea I actually like. You could even mount the diff. point upward instead of sideways and run a pulley off a vertical shaft. There is one thing to be said about a mechanical connection... it usually works. The windmill looks like it needs 70MPH to work right, the alternate alternator would require brackets and belts attached to existing motor AND would require electrical connections from said alternator to trailer where the action is.
I'm afraid I'm going to have to side with OP about the PTO idea I like it.
That would certainly add to both the complexity and ease of design.. I like it Jim. Great thought there. Would def have to create a full diff protector in that design approach too. And after thoughts, you seen the issues too.
