A/C and generator use--ettiquete, practicalities, technology

A newby question:
I'm not a fan of sleeping in the heat, and (more important!) neither is my wife. So, if we are gonna camp in a TT in the summer months, that means running the A/C at least part of the night and (consequently), a generator if we're not on shore power. The generator would be a quiet Honda or Yamaha unit.

1) Is it common for campgrounds to forbid the use of A/C at night (due to noise) when plugged in to shore power?

2) In what places is it generally allowed/accepted to run a generator and AC when it is hot (incl at night)?
a) Private campgrounds?
b) State/federal parks? (Different rules for "dispersed camping")
c) Walmart/Flying J, etc?

3) Are there any super-efficient camper/AC combinations that allow cooling on battery power? I'm guessing a camper with a FG/foam composite shell (r-8+) with small surface area and a very efficient AC unit (Peltier or other solid-state unit) might be practical, at least in theory. Or, a 10 lb block of ice in a cooler with a small fan. (I can crunch the number on that).

4) Are there small, affordable AC units that use propane for cooling (absorption cooling, like a propane 'fridge). It probably wouldn't be very efficient, but it would be quiet and (needing just a fan and no compressor) could probably run for a night or two on battery power with some help from solar panels.


Thanks!

Hi and Welcome to the group Mark.


What you are asking is a very popular topic and there was a string of posts on the issue just last week. But I am afraid that you won't like most of the answers to your questions:


1. YES, most campgrounds set "Generator Hours. Some require shutting them down as early as 6PM, most by 8 PM and almost all by 10PM. Your tenting neighbors really don't want to listen to a generator, much less be downwind from the exhaust.


2. Pretty much the above applies at all kinds of campgrounds for generators, most places with hook-up seem to not mind a/c running at night. About the only safe place might be truck stops.


3. Battery powered cooling systems, for the most part, aren't defined. There really isn't a system that will work on 12 VDC short of carrying a huge battery bank and inverter system, but that would put most FGRV's over weight limits.


4. Nope... but if you invent something that is able to do that you could make a bunch of $$$$$$


BTW: It's assumed that everyone will be running something like an inverter generators with rated noise levels at least below 62dB. The old 3600 RPM generators are banned in a lot of parks.


About your only sure bet is to only hit sites with hook-ups

We've camped in all kinds of weather. We've found that two things make for more comfortable night in hot weather. If possible park in the shade, this keeps the trailer cooler. We also carry a "Constant Breeze" 12volt box fan, it may not cool the air the breeze blowing over you will help keep you cool.
One beauties of trailer traveling is that if you don't like the weather where you are you can move. I realize that this is more difficult for "week-enders" than long term campers. However, I would think there's places even in Ohio that have pretty cool night even in the hot summers.

If you want to run your air conditioner all night your only practical option is to pay for a site that provides electric hook-ups. Of course, that likely means you will get no sleep. They ain't quiet. There is no air conditioner I know of that can run on battery power, even for a couple hours. Then, your batteries are dead. Any generator running all night, even if you dare do it at a truck stop, could result in your finding it not there in the morning.

Since solar has become reasonable priced, the use of generators has become increasingly unpopular & more and more restrictions on usage as a result.

If allowed most campgrounds will restrict the hours of use of a generator - not just at night but mornings as well. Often only permitted for a couple of hours at a time. Its normal to be restricted at Public or Private campgrounds as well as some Forest service campgrounds - I have actually stayed at a Forest Service Campground as well as a Public campground that did not allow any generator use.

I parked at a Walmart and there were two campers using a gen. I was surprised that one would do that. It was not for AC it was cold out. Carl

The price of solar may be coming down although I might quibble as to whether it’s reasonable. Reasonableness, I think, depends on one’s expectations. But any question on electrics does bring out the solar fanboys. For me and the places I prefer to camp (shady sites) it (solar) is largely useless. I’m a gadget freak and therefore solar appeals to me but I’ve been able to resist it because there is insufficient payback for me in terms of recharging.

But, even ignoring compressor startup, the electrical needs of current A/Cs are so large as to drain a battery (through an inverter), in less than an hour (assuming the 50% battery drain rule of thumb). Wanting badly to do something is not sufficient to overrule the physics. Running the A/C all night on a battery is one of those options that is denied us. We are forced to look for powered sites and forced to endure the temperature if without “shore” power. I haven’t run across a campground with a complete ban on generators yet but all have limited usage to 10pm or earlier. Stirring the air with a 12v fan seems the only option at the moment for those times stuck without a power post.

I'm with you....I HAVE to have an A/C to sleep comfortably in the deep south's humidity. Been there TRIED that without it in August one night. It was awful and killed camping for me for YEARS! (Was camping with my parents in an old camper he'd found).

I would HIGHLY suggest scouting out and calling places you plan on going before counting on a generator. You can make neighboring campers very upset with gens. The Hondas are alot quieter. I have a Champion 3500/4000 which is PLENTY of efficient to run my heat strip OR the A/C for 8 hours plus. But it's loud and I can rarely use it...but rarely need it since I stay on the grid most of the time.

OR ones history/experience with solar. First 15 watt solar panel and controller purchased for current trailer 7 years ago cost C$160. Daily Operating cost & maintenance cost for 7 years of use $0 & it still works and will be put to use by another family member on their trailer. to maintain battery. Recently replaced with 60 watt panel (4 times the watts of original panel), new controller (better quality than original & weather proof) & all wires and connections for C$110 recently..... again no daily operating or yearly maintenance cost. Not to mention the freedom the solar gives me to camp any where I want without having the neighbours glaring or yelling "shut it down". That to me is Priceless!

What does a generator cost these days? What's the cost of daily operating? Price of gas per gallon? Maintenance costs for generator in 7 years of daily use when camping/using 120+ days a year?

Totally agree though that where and how one camps & comfort level one expects does have an impact on whether or not one can live with or live without a generator. Have camped many days in temps in the high 90's low 100's with no AC - just a good 12V roof fan and still enjoyed the time spent camping

One just needs to be aware that these days depending on where you are camping there is a fairly high probability that the neighbours may not agree that a generator is really needed.

In thinking about this topic it amuses me that back during my Boy Scout days we would camp out all year in a tent and not think anything about it. Now I would DIE without A/C in the Summer Florida heat/humidity. And I am not sleeping on the ground anymore either. In answer to the question I would say just plan your trips according to the season. Summer, make it campgrounds with hook ups. Spring/Fall, go boondocking.

That's because you played and had adventures all day. When you were tired you slept. But now the kids don't have the physical activity except their thumbs and they wan't more electrical power than you do.

Now adults hide out all day and wait for 5:00 for cool down libations. Not allot of activity to burn you out to sleep no mater the weather.

Its funny to go camping and see all the cellphone charger's plugged into the bathrooms electrical since the sites don't have power.

In days gone by people had screened porches complete with beds. When the night got so hot it was hard to sleep, off to the porch you went.
During my backpacking days when the tent was hot, or when I figured it going to be a warm night, the sleeping went on a ground cloth and the stars worked a ceiling.
Now everybody wants to burn up fossil fuel as much as possible.
