Wind Generator?
Solar and batteries. I get it. That's the standard suggestion. But, I've also spent many nights in windy conditions. Would love to charge at NIGHT too! Or cloudy, windy days. Does anyone have any e...

Amazon: Pedal generator
If you read the specs, this only puts out 20w. I'm assuming that is peak output so figure closer to 10w plus some losses converting to 12V, so less than an amp going into the battery bank.
You could build a real pedal powered charger but an average adult can put out only around 100w if pushing hard for an hour. That's about 8amp-hr into a 12v battery (not much for an RV battery bank that might run 200-600amp-hr). World class cyclers can only get that up to around 400w for an hour or about 32 amp-hr. Keep in mind this is pushing hard for a full hour. 20 minutes at a leisurely pace will be far less, might only generate 1 amp-hr.
Thanks for that analysis. I supposed that the output would be small and mainly my post was in jest. However, if the price wasn't so high I would consider doing it as I am serious about finding ways to get exercise on the road. We will probably do a combination of hiking, biking, gym membership, and some stretch bands and light weights in the RV.
