Kathy and I are heading toward Big Bend National Park after work Thursday afternoon. The plan, depending on how early a start we can get, is to spend
Thursday night at Hal Kading's business at the Las Cruces airport, then head to Marfa, TX for an overnighter at the Marfa Lights Viewing area on
Friday night before heading to Rio Grande Village on Saturday for a several night stay.

These are all dry camping locations. The problem is that, depending on which weather forecast you look at, the overnight low in Marfa is supposed to
get as low as 22 degrees on Friday night. I'm not worried about the inside plumbing freezing since there will be two warm bodies emitting a few BTUs,
albeit under a stack of blankets, and we can always kick in the furnace, but I am concerned with the macerator freezing and sustaining some damage.

Is this a legitimate concern? Should I run some RV antifreeze through it before we leave (we won't be dumping until we get to Big Bend)? Or should I
just not worry about it. I think the coldest dry camping we have ever done has been at Joshua Tree National Park, about five years ago, but the temps
only went down to the high 20s there and it warmed up nicely during the day.

Thanks

Carl,

I am jealous. I was part of building a fiber to the Home project south of Marfa, TX years ago, and was amazed at that crazy town. that area and
Big Bend park is on my bucket list of places I hope to someday spend some time seeing in the GMC. make sure you get a good photo of your GMC sitting
by the Prada museum.

As to your macerator, I personally don't think you will have any issues, as it will warm up during the day, so you are not talking any "hard freeze".


but if you are overly concerned, you can either wrap it in some insulation. or at the time you dump before you deal with freezing, pour a quart of
antifreeze in the toilet, and bump the macerator button a couple times to get that mix into it.

I usually have my macerator full of antifreeze(green), when I let it sit for winter. Last thing I do when I final winterize, is to get green out of
the hose into a bucket.
I then have used the tank itself, and not worried about the macerator freezing. I tried to put rock salt into the black tank to keep the liquid in
that from freezing, but I am not sure that helped any(you don't want rock salt in the macerator... when I use my black tank in the winter- I am
dumping via the 3" dump). Last time I did that, when I went to drain the black tank, water drained out, but there was a 1/2" sheet of ice midway up
froze across the entire tank. ended up having to blow hot air down the toilet for a while to get that to thaw out on a warmer day(for me that is
like 25 degrees out).

We now have -100 rated antifreeze(think it is boiler antifreeze- I am not sure as we get it in 50 gallon drums) we use everyday at work now. So I
will probably switch from green to that next time. We are having to winterize everything constantly at work, because now everything(hammer drills
and core drills for my crews) has a water hook up for dealing with drilling because of the silica.

Carl,

During the first years we had the coach, we travel in the late fall. (Snow is common in late fall at our latitude.) While I did have a macerator, we
never had issues with the potable plumbing even though we were not interested to run the LP heat (all we had).

Here is a good part. Many places use urea as an ice remover. It is better than salt. (More expensive if purchased unused.) If you limit your
potable water use and do use the head (toilet), you should have enough antifreeze in the black plumbing naturally.

This is why I put the macerator install on hold. Been caught with rapidly dropping temps in the fall. Last episode was October in Limon Co where a
sandstorm came up at dusk, Coach was rocking up and down for hours. Couldn't open door due to wind. At sun up the camp water spigot was frozen solid.
Driving to Limon the dash AC was on. Mother Nature can really turn fast. Keep us posted on the macerator. I would like one especially for dumping at
home so I don't get stuck on my own grass again!

Thanks for all the great advice and suggestions. I rebuilt the valve coming out of the tank when I replaced the waste tank a few years back, but I
don't think it's sealing well enough to keep the macerator dry. I'm guessing I will not have a problem with it based on what Matt said about the
'natural' antifreeze, but I will probably drag myself under the back and zip tie some insulation around the macerator just to be on the safe side.

I remember Dan Gregg telling me that his macerator froze one time and he had to wait until it thawed out to empty his tank. It is such a small area
that has liquid in it that I'm thinking it could freeze without cracking it. I will report back.

Carl, I've had it both ways so to speak. I had the macerator freeze and break while parked outside at home in Rio Rancho BUT, just this past
Thanksgiving survived 1 degree weather at the Grand Canyon without harm-go figure. Of course I didn't try to use the pump at those temperatures but it
managed to live through the deep freeze.
Have fun, Hal

Thanks Hal,

Like I said, I'll drag myself under the coach and wrap some insulation around the pump and hope for the best. If it freezes, it should be good to go
by the time we get to the campground at Big Bend, and hopefully it will be a little warmer there.

I carry a clip on lgiht in a round reflector for things like this. 60 Watts overnight doesn't kill the little inverter I have and the light clipped
under and aimed at the macerator will jkeep it from freezing. Where there's electric hookup I skip the inverter and save the battery.

You might want to install a small heating pad on the bottom of the macerator before covering it with insulation. They come in various wattages and at
12 volt or 120 volt.

The following one is 20 watts at 12 volts with the heat applied directly to the macerator. That is less than 2 amps draw. We use them at 12 volt
for diesel fuel filter heaters. Some also come with built in thermostats.

Look on Aliexpress or Banggood if you do not find what you want here on ebay.

Another option is heat cable. Comes in 120 volt, 12 and 24 volt variety.
Various lengths with accordingly different resistances (wattage ) just wrap
stuff and plug them in.

We use the fresh wate RV antifreeze full strength and put it down the
toilet and run the masserator so it fills up with that fluid.
Car antifreeze is not considered to be dumped .

Heat pad is a good idea, but I don't think I have time to get one at this late date. Maybe a 12v light bulb as a heat source. I have done as Johnny
B suggested before with a light underneath, but I won't be plugged in and I hate to have the extra draw of the inverter all night.

I haven't installed my poop pump yet so no experience there.
I have had a washing machine pump freeze twice, dumb tenant can't close a door tight, thawed it out and still works fine.
I'd just leave it be.

I had some heavy duty fireplace insulation left over from when I insulated the gas tanks, so I wrapped some of that around the pump. zip tied it in
place, and I'll call it good. Hoping for the best.

Ron,
I don't think it was below 10 but we had some wind which probably did it in. I was pleasantly surprised we had no damage at 1 degree though.

For your short term need of a couple of days not colder than 20 F:
1. Dump the Black tank
2. Leave the valve open and drive the coach around for a couple miles and up hill if possible.
3. Bring it back and close the valves.
4. Get 3 gallons of RV antifreeze at Menards or Home Depot or TSC.
5. Dump at least 2 and probably 3 gallons down the drains of the kitchen sink, bathroom sink, and floor drain. You will end up with close to 3
gallons in the black tank which should mix with anything still there to lower the freeze point at least 10 or 15 degrees which is all you need. It
will cost you $10 or $12 plus the gas from driving and will give you cheap peace of mind.

Also, keep in mind that the fresh water system can freeze , so we leave the
lower cabinets open to allow warm air to circulate at night when the temp
is lower and the water is not used.

Okay, so the macerator survived the 19 degree night at the Marfa Lights viewing area unscathed. Yay! I don't know whether it was the 'natural
antifreeze' or the insulation that did it, but it worked out fine.

As to Kathy and me, we piled a couple of extra blankets on the bed and toughed it out until morning when we switched on the thermostat and took the
chill off with the propane furnace. Actually, we were quite comfortable. Man, it sure gets cold on those West Texas Winter nights! We used more
propane this time than we ever have on a trip.
