Not necessarily Bob...I camped in a different campgrounds in Pa that offer very minimal electricity...enough for my microwave but not enough for the ac unit. They mention in the form you sign no air conditioners to be run off their ac ...generators are fine. A few people up near where the ac lines start might get away with it but on the other side of the camp there would be no power.

Ace of Diamonds Herkimer mine sounds from the feedback a touch ghetto lol but they are supposed to be much friendlier then the koa camp up the road(and a 3rd cheaper)

Some campground owners don't like a/c's because they are often run 24/7, playing havoc with their power bill, whereas microwaves just run a few minutes a day. And the generator noise doesn't bother them as they aren't sleeping right next to one.

I have been in campgrounds where power was one price, but adding an a/c raised that price.

Yup but sadly both the ac and the microwaves seem to have a direct relationship to the generator. While the microwave will only run for a few minutes a day it sucks back enough power that one requires the generator to run for an hour to put the power used back into the battery.

Been to a number of campsites in recent years - both public and private and forest service areas were generators are not welcome even on reduced hours of use.

And I will avoid those kind of parks/camps during the summer. Spring and fall I no longer need it....hot humid summers and wintertime different story. I was camping in Pa last weekend and actually fired the heater on for a bit in the morning, it dropped down to 50'. Short runs with the blower fan my solar panel will recover it... running the furnace 24hours straight....need either ac or a generator.

As you can see we have generator haters and lovers. Sometimes for me its just a needed tool. I'm not going to stay home on a weekend just cause its going to be 90+ degree's and real humid. Daytime I can deal with it... night time I want a level of comfort. Hence why we are in campers and not sleeping on the ground staring up at the stars like the cowboys did lol.

Seems like it would make more sense to run the generator for a few minutes while using the microwave...

This is something I recall and to some extent have tested in a limited way.

Deep cycles as a general thing (at least flooded ones that are true deep cycle) do not take a fast charge well, any more than the can deliver a fast discharge as output to start a car. The newer marine/deep cycles may not be as slow to take a charge because they are designed to deliver a starting charge. IDK for sure.

Had to do with the difference in the plate surface area of a deep cycle limiting the rate at which it could take a charge.

As for my testing it was a small gas engine hooked to spare alternator from school bus with a regulator. Using a larger pulley on the engine I could increase the rpm's of the alternator to crank out more amps. But had to run the engine at 3/4 throttle to have enough power. Guy at battery store said that was fine for jump starting but for charging a deep cycle I should try smaller pulley, lower alternator rpm's and run the engine at lower throttle. Tried it and it seemed to do a better job putting a charge on the battery with less noise and fuel used. Took awhile to get that charge however.

Me thinks a modern smart charger would do the best job of charging the battery efficiently using a generator. Using solar I would think a good charge controller would do the best job.
