Hot Time in Pinesburg

Pinesburg? Where the heck is that? That happens to be the closest named "town" to the Hagerstown/Antietam KOA, where we spent this past weekend.

Despite the heat (temps were near 100°, with a heat index about 15° above that!), we really enjoyed the weekend. The campground was quite nice, and our waterfront site was perfect! For the whole weekend, we did little more than watch the Conococheaque Creek go by -- along with the occasional kayakers. I'll let some pictures tell most of the story:

We actually managed to not go into the trailer and use the air conditioner for most of the weekend. This was my view from the dinette table at breakfast on Saturday morning.

The weekend was a great test of temperature control. The fridge did well, athough the temp did climb to about 48° in the box at the peak of the day. That's a little warmer than I'd like, so I'll probably take a couple more steps to get that down another couple of degrees.

We'll also definitely be adding Reflectix panels over the bunk ends. It was easily 10° warmer in the bunks compared to the main area of the trailer during the daytime -- the canvas was actually quite warm to the touch. Still, Friday night and Satureday were pretty comfortable with all the windows opened, and without the air conditioning (though we did succumb to the heat and turn it on Saturday night).

Of greater concern was the van. When we left Friday afternoon to head out, we had no idea how that aging beast would do towing the trailer, running the air conditioning, and battling hills in the stifling heat. All in all, it did okay -- and a lot better than some other folks who were out for the weekend. However, we did run into cooling issues when running the air.

While it never actually overheated, the temperature gauge did take a couple of startling leaps. So, for the trip home, ditched the AC and just used the old 2-55 units (opened the two working windows). A check of vital fluids after we got home and everything cooled off showed that we were still all good on coolant, oil, and transmission fluid. Gotta love that old Grand Caravan! It's a trooper! I think we're going to happily dump a few dollars into it and buy it some additional/larger auxiliary cooling.

The Kitchen Fix(es)

I previously mentioned that a couple of screws in the hinge for the kitchen top unit had pulled loose. I initially thought that it was because there was no support for the front edge of the kitchen when it was flipped over for travel, and that may still be the case in part.

However, the real culprit was a small block of wood, we think intended to keep the fridge door from swinging open too far. That block of wood was resting against one of the cabinet doors, and putting outward pressure on the entire unit.

As planned, I proceeded to replace the two pulled out wood screws (they actually used sheet metal screws) with T-nuts and bolts.

My first activity was to drill a couple of exploratory holes to see if the existing holes would be  usable. I found that, in the case of the outermost hole, the exit would have been too
close to a vertical brace to get the T-nut installed, and the second screw had been put in at an angle that brought the exit at the very front edge of the cabinet frame. So, no bueno.

I drilled a new hole in the hinge for the first, and re-angled the hole for the second, installed the T-nuts, and tightened everything up. The tightening actually took a couple of repeats, as I was working with the T-nuts upside down, and if I went in too fast, gravity would remove the T-nut from the hole.

Notice that the screws I had were a little too long. To avoid snags and getting cuts when getting things out of the cabinet, I trimmed them off with a hacksaw blade in my saber saw.

All done. Nice and tight.

Future Kitchen Updates


I talked to my friend Kevin yesterday about how he'd go about adding a tankless, on-demand water heater (the thought was to add an electric on-demand unit). He had a couple of interesting comments. First, he suggested that I may not need as many check-valves as I thought -- the one in the 12V pump may be sufficient to keep city water from back-flowing through the pump into the freshwater tank. But, more importantly, he mentioned that on-demand water heaters are very susceptible to less-than-lovely water. In addition to various particles, water that's too hard, or to acidic will cause premature failure. The Camco TastePURE filter we're using gets all the contaminants, it does nothing to affect pH or hardness. 

Kevin did mention that it's now possible to get roughly 3-gallon water heaters, though, which are less susceptible to imperfect water. The downside to a "traditional" water heater is size and weight, but they often cost less than the on-demand units.

We've been discussing a deeper sink. The one supplied is about 4" deep -- fine for washing hands or rinsing cups or small dishes, but that's about it. Also, we're thinking of removing the stove, and making it an outside stove. Should be relatively easy to remove and fill the gaping hole in the counter. The challenge part will be adding the gas line to the outside of the trailer (it's not setup for an outdoor kitchen at this point).

Update on the Fridge


It's about 95° (that's 35° for those of you who use the funny numbers) outside here today. A peek in the fridge puts the temperature at about 35°F or 1.7°C inside the fridge. This was with no air conditioning running -- just the fan modification. And, as Karen mentioned in her comments, the fridge will be easier to get and keep cool when is filled with cold stuff. So, as the kids say, "Aces!"

The fridge fan mod does need a little refinement -- one of the fans is rubbing a little bit on something, so it makes a little "ticking" noise. Also, I want to reverse the door on the fridge, so one night this week, I'll take all that apart...

A fridge should be cold...

I mentioned the other day that, due to the nature of most RV refrigerators, they struggle to keep food at a safe temperature in really hot weather -- anything above about 78°F. I did some research on the interwebs (Google and YouTube are your friends!), and found that it's relatively easy and inexpensive to get some help for cooling system in the fridge.

The gist of the problem is that air's not moving over the cooling fins in the back of the unit, and the trick is to add a couple of fans back there. I decided to give it a try and see if it would help. I did not make a video or take many pictures, as there are a hundred good videos out there already, including the one I've inserted into this post:



The whole job only takes a short time to complete, and it does appear to work. When I was done the job at just past 3:00PM, the temperature outside was about 90°F, and the temperature inside the fridge was about the same(!). I fired up the fridge and decided to see how well it worked running just the refrigerator (no AC in the trailer). At 8:30PM or so, the temperature in the fridge was down to just under 40°F. Now, there was some natural help involved. We had a thunderstorm roll through, and the ambient temperature dropped to about 75°F, but before the storm, the fridge had reached 50°F in less than three hours. For an absorption unit on a hot/warm day, that's pretty darned impressive.

200mm fans strapped to the inside
of the upper fridge vent.
I was able to get two 200mm fans for about U$15.00 each at the local Micro Center -- and wire I had on hand. The fans I used were their "Thermaltake Pure 20 High Airflow Sleeve Bearing 200mm Case Fan". I think they're the same ones used in the video, except without the gaudy red LEDs. For their size, and the volume of air they're capable of moving, they're incredibly quiet.

Mine's a little more ghetto at the moment, as the only cable ties I had on hand were the plain white ones instead of the sexy black ones. I also couldn't find a suitable switch today in my travels, so for now I've got the fans hot-wired straight to the 12V feed to the fridge, so they can't be turned off. Eventually, I will want to add a switch. Otherwise,  the fans will eventually run the battery down if the trailer's not plugged into either shore power or the tow vehicle.

Of course, we'll monitor the fridge over the next few days, but so far, I'm calling this little mod a success. Some folks also suggest some circulating fans inside the fridge, and we'll probably add one, too, just because. And, we'll get to test the mod "in the wild" in just a few weeks, when we venture out to Western Maryland for a long weekend.

Update 11 July: Fridge was below 32° this morning!
