The polar cub sounds perfect for my 8 ft Lance except maybe for the price. I mostly use my camper fall and winter to hunt, but would use it 6-10 days a year for summer trips, if I add a roof air conditioner. A high profile Duotherm brisk 13500, would cost about $550 and the low profile alternatives appear to run at least $300 more. I don't use a generator. It's either dry camping for me or full hookups.
The Lance is all prewired so I plan on installing it myself.
The 4 or 5 inches of height difference won't cause a problem pulling in my shop.
So my question is, are the advantages of the lower profile and the lower BTUs worth it for my limited summer use? Does one run significantly quieter?
There are a couple of more reasons that the newer 49201 is quieter. (With the 'green gas' change, the 9200 is no longer available and the 49201 is the only one available after 2010)
First, 11k and 13.5 units blow a rated 350 cubic feet of air per minute; the 42901 blows a max of 200 CFM. Moving less air makes less noise. There's no jet-engine roar by comparison.
Second, the 49201 unit operates under much higher pressures so the manufacturer had to build the unit with heavier components, particularly the copper tubing up inside of it.
It also has a beefed up compressor. The result is that less mechanical noise comes out of the unit in operation because of the thicker tubing and heavier or thicker parts.
I just replaced the 13.5 BTU in my T.C. with a 49201. I couldn't be more pleased. I equate the new noise level to about that of a running microwave oven. Actually I can't tell much difference in noise between low and high speeds.
I just checked the pics I took during the install...we have the 49201. It's been running perfectly. We installed a new thermostat... recommended by a/c installer and I think it was a good thing to do.
So my question is, are the advantages of the lower profile and the lower BTUs worth it for my limited summer use? Does one run significantly quieter?
See my other comment about the quietness.
Air conditioners 'condition' the air as well as cool it, thus their name. They are not advertised as air 'coolers'.
Conditioning means removing the humidity so our skin feels better in the drier environment, (as well as cooling the air).
Your skin in 72 degree air, saturated with humidity doesn't feel that great, but 72 degree air void of most of it feels crisp and comfortable.
If you installed (jokingly for example) a 5 ton a.c. in your camper it would drop the temperature quickly and the thermostat would shut off, having done its job.
But the effect of removing the humidity takes a long while. Therefore, a 'matched' size unit, (in our case, as small one) will take its time about both getting the temp down, and during that longer process, remove more humidity, than a fast acting, larger unit that shuts off quickly after reaching it's set temp.
