There has been a lot of discussion on various thread about how the new Oliver
performs in the cold. Since this has been the coldest weather any one of them has experienced so far, I decided to do a little testing.
First some parameters and disclosures:
I am in Tupelo, MS usually not one of the coldest spots in North America especially in mid November. However, as I am writing this, it is 28̊ outside with tonightís predicted low of 18̊. As a comparison, on this day last year we had a high of 72̊ with a low of 64̊.
Our trailer is inside a metal building. The building is unheated and completely open on one end. It does stay about 3̊ or 4̊ warmer than the ambient temperature inside probably due to the heated trailer sitting there.
Although I do ďwinterizeĒ our trailer, (I drain the water and blow out the lines, no antifreeze) I keep it heated with a small heater I got at Wal-Mart. It sits on the floor about half way down the center aisle pointing toward the rear. I like to keep the interior around 60̊. Sometimes I like to go out there and take a nap or read and I want it to be comfy.
We have two digital thermometers inside mounted more or less at either end of the trailer. One is simply the remote for the Amazon.com: Maxxair 0007000K MaxxFan Deluxe Fan with Remote and White Lid: Automotive
which has an onboard digital readout, the other is a La Crosse Technology Wireless Weather Station Alarm Clock - Walmart.com
that you can easily deduce from whence it came. There was one remote transmitter supplied that we mounted under the propane
cover outside and it sends the information on the exterior temps. We added another remote transmitter that is mounted inside the refrigerator
to monitor the temps there.
cpaharley2008 had tweaked my curiosity about the possibility of being cold sleeping right next to my windows
. Since I had purposely designed our beds to top out right at the level of the windows
, I wondered if maybe Iíd not thought that through.
We have double pane windows
throughout the trailer.
I used a Non-Contact Infrared Thermometer With Laser Targeting
to measure the interior and exterior temps. This was all done within about a 20 minute period so there was little to no temperature fluctuation.
The two digital thermometers both read 61̊ for the interior temperature.
All interior walls were within 1̊ of the above interior temperature.
All exterior walls were at 31̊ (just barely warmer that the ambient outside temperature).
All interior window panes were about 59̊
All exterior window panes were about 37̊
The interior of the door was 54̊
The exterior of the door was 31̊
The interior of the door glass pane was 54̊
The exterior of the door glass pane was 44̊
The floor was about 56̊
The ceiling was about 66̊
In the basement and between the shells (where all the plumbing and tanks are) the temps varied from 45̊ to 50̊ as measured on the foil surface of the reflectix insulation glued to the inside of the exterior shell.
There was a 30̊ difference in the temperature of the inside and outside shells.
There was a 22̊ difference in the temperature of the inside and outside window panes.
There was about a 2̊ difference between the interior wall and the interior window pane.
The door is purchased as a standard RV model with a dual pane window and is not manufactured by Oliver
. It is obviously not as well insulated as the rest of the coach, but it is at least as good as the coach windows.
There was a 23̊ difference in the temperature of the inside and outside of the door.
There was a 10̊ difference in the temperature of the inside and outside door glass panes.
There was a 10̊ difference in the temperature of the floor and ceiling (heat rises).
The reflectix insulation affords about a 15̊ temperature difference on either side of a single shell. Since each shell has its own layer of reflectix, this accounts for the 30̊ difference in the temperature of the inside and outside shells.
Does all this qualify the new Oliver
Elite II as having 4 season capabilities? I couldnít tell you. But I do know that itís below freezing out there right now and not even using the furnace
I could easily get the temperature up to about 80̊ inside with nothing more than that little cube heater. Thatís way hotter than I want to sleep.
