If all you were using it for was to top off batteries, you could barely even hear it from the next campsite.

I was shocked... and I really mean shocked... the first time I fired up the Onan in the Paseo. Unbelievably loud, and the vibrations from it can be felt throughout the entire vehicle. Love everything else about the Paseo, but not that generator.
The genny I bought was $779 at Amazon yesterday.

I paid about $900 for mine. Post Maria, Irma and I forget the other name.

Just in case folks wanna know.

It makes sense now that you mention you haul a trailer with you.

Any generator, quiet or not, has restrictions in a campground be it totally banned in use over all the campground or in certain areas. Those area where acceptable are generally where big rigs park and everyone runs them. If allowed, then there are restricted use from not overnight down to a couple of hours in the morning and evening. They are not good for stealth. I knew that as early as the 70's when my parents parked out on the street and ran their generator. My neighbors were all up in arms. They intrude on nature's peace and quiet in off-grid forested areas. I don't have a generator now. My previous B had only about 20 hours on the Onan over 65,000 miles of travel and the majority of those hours were "exercising" hours over winter storage. I had not much use for it and managed do do without with two lead-acid batteries.

I guess the point I am making is if you grow dependent on generator use then you restrict where you can camp.

I tend not to use much power while boondocking though the new style Dometic fridge does not help in this regard. An average would be 20-25 amp hours, unless it's cold enough to run the jet engine, er, um the furnace quite a bit. I have no intention of running a Microwave/toaster oven or other heavy use from the house battery.

I have 150 watts of portable suitcase style solar collectors fed through a Renogy PWM controller.

My conundrum. Due to the slow finish charging of the batteries, I'm thinking I would be better off with one battery vs two. I would still be good for basically three days with no help from solar running one battery. I'm thinking cuz of the slower finish rate two batteries may have a much more difficult time getting to full charge versus just one, creating an environment where the batteries would spend several days to a couple of weeks not getting full.

I really don'r have the need or inclination to get more solar, though the controller is rated at either 20 or I think 30 amps.

If for some reason there was a lack of solar or extra demand I have no issue running my nice quiet Champion remote start inverter genny for a while.

Thoughts? Am I just being too anal and I should mount up 200 amp hours of batteries?

The RT is a 2000 Chevy 200 Versatile.

TIA.
You're a Spartan road warrior so stay light. Given your user profile one battery will be twice as reliable than two during the five year life of the batteries. If you want a little more capacity, one high capacity battery is much more reliable than two. If you had two would they be
1) strapped them in parallel so the weaker battery always drains the good one?
2) issolate each battery with a schottky diode and let the 0.5v drop inder heavy load waste 4% of the battery's energy.
3) swap cables so you use one at a time and miss the fun.

Buy one and size it to your application.

There were comments in this thread on charging two batteries using the regular engine alternator. There is a 50 Amp breaker on each end of the 12v line between the alternator and the house battery.
I would imagine that if both house batteries are quite low, the alternator might have to supply 50 Amps, or maybe more for brief periods before one of the breakers interrupt the circuit temporarily. The alternator will also be supplying current to the engine battery and coach systems at the same time. Can this put a stress on the alternator, or is it designed accordingly?

50 amps plus maybe 15 to run the van shouldn't be too much for the alternator, depending on how big it is. It would likely be over 100 amps and it wouldn't be running at 50 amps for long. If the OP were going to charge that way a lot, and newer, larger alternator might be in order, but probably not needed.

Good perspective.

I was really bummed that I had to replace my old style mechanical fridge with the new stuff with a circuit board and it's accompanying current draw. I was able to get by with a group 24 battery just fine.

The single battery I have is a "maintenance free"Ever Start Maxx flooded rated at 78 amp hours. Your typical Walmart cheapy though it states it's good for 30% more charge cycles. It's about two years old and still functions as new. Since adding the new fridge, it drops down to about 50% or lower if I have to run the furnace quite a bit, hence the desire for more battery.

Most of my camping is out west so solar is pretty decent.

I do not have a Tri-metric but do use current/power monitors.

https:/amazon.com/gp/product/B01JOUZELG/ref=oh_aui_search_detailpage?ie=UTF8&psc=1

The battery that I was leaning toward is a group 27 flooded "maintenance free" Exide that Rural King sells for $69 or 79 depending if on sale when purchased. They carry three allegedly different group 27 marine/RV batteries, start, start/deep cycle and deep cycle. The deep cycle is rated at 105 amp hours. All three do have different specs/ratings.

I'm thinking this will likely work as it will give about 20 more amp hours of usable power than I have now, 78 vs 105. 58.5 vs 78.75 amp hours when discharged to 75%. Assuming a plumb full battery.

My current thinking is to roll with that battery and see what happens. I do like the low $$ buy in and if it goes for two years at that price I'm a happy camper. More, which is likely, is a bonus.

That being said, I will design the new battery holder to accommodate a larger battery.

Background info. My retirement funds are not unlimited. Hence the now 18 year old RT. I do try to keep expenditures to a minimum but still keep things workable. I do stay after preventative maintenance using a good brand for parts(Gates, Delphi, Wix, etc). It tends to cost more not to do it. And it's a lot more inconvenient not to. I intensely dislike having a breakdown when traveling, hence the disappearance of the Onan from my life. I recently sold a motorcycle with 234,xxx miles on it. Due to preventative maintenance and a bit of good luck, it never left me stranded on the side of the road.

I would like to thank all that have participated. It's always good to get different ideas and perspectives.

Now to go pack it for an upcoming four month trip out west.
