Temperature Rating

[rames14]

I know Montana makes a big deal that our units are rated for 0 degree weather. What about Mountaineer and High Country? I don't see a rating on those units. I believe the R factors are the same, but does that translate to the 0 degree rating? I am sure someone already knows this answer.

Ron, if you get the brochure(online at Keystone RV) and down load it, you will see the zero degree rating on the last page of brochure for the Montana Mountaineer, the Montana HC, does so the same R ratings. Also look at the suspensions, when you look at the rig, the Mountaineer shows the CRE 3100 in the brochure, but out new 2015 was delivered with the CRE 4100, the HC comes with the CRE 3000. For what its worth, we are really liking the new Mountaineer and we traded the 2012 HC for it. You wouldn't like our model though, 39'7" listed and actual is 41'10", 13'4" tall. And I know you are looking for something in the 35' range, good luck and happy searching.

Don't know the answer but I can tell you that we were recently camping in 34 degree weather near Gunnison and the furnace was working overtime keeping the RV at 68 degrees.
As a result, one of my mods to be completed before next camping season is to thoroughly insulate the rig. I'm looking to follow the lead of others on the MOC forum to accomplish this.
0 degree rated? Maybe for Nanook of the North, but not me.

Thanks, John. We just had a new pad put in for our 365REQ, which is less than 38'. It was all we could do to get it so we wouldn't scrape. The rig was hitting at the ladder. We are extending the culvert which will give me a straighter run at it. At least we have taken the drama out of the hill. Jay, you're getting soft as you get close to retirement.

That zero degree rating is all a marketing ploy. Any manufacturer of any brand can claim whatever they want. Can you use it in zero degree weather? Sure, you'll just never be warm. Can you use it in 110 degree weather? Sure, you'll just never be cool.

Last winter, prior to finally being able to head south, we were in overnight lows in the single digits to the low teens. We were very comfortable inside, and had no issues with frozen plumbing, but all that at a cost of having to fill a 30 lb tank of propane every other day. We would turn the heat down at night to maybe 65 degrees, and the heater did not run all the time, but it was quite a bit more than when in the above freezing range. So, common sense tells you, no matter where or in what kind of structure you are living, you will use more energy to keep warm, the colder it gets. Keystone might put a disclaimer along with the 0 degree pitch that says you will use much more propane to manage the cold temps.

Tom, I am only wondering if it is insulated to the same standard as the regular Montana. We've had a 2005 Montana (prior to the zero degree "rating") and we've got a 2010 Big Sky (with the zero degree rating). Just looking for equivalency. We frequently camp when it's in the 20's, and living in the mountains it is a question I wanted answered as we look for a shorter unit. Thanks, Bob. We have seen propane usage increase as the temp decreases. It only makes sense. Again, merely looking to see if there is a difference between the Montana, Mountaineer and High Country from a rating standpoint.

As you mentioned, all three models have the same R ratings: Roof = R-38, Walls = R-10, and Floor = R-21. I would think that would mean that the "ratings" would be the same, but the wording on the brochures is different. Here is a link to all the brochures: Brochures
Interestingly enough, when you read through them, the Montana and High Country do refer to the 0 degree rating and arctic ratings. Then you can look at the Mountaineer and High Country and they both refer to "glacier package". Another interesting aspect to the brochures, the Montana plainly specifies a 35,000 BTU furnace, yet the others do not specify the furnace ratings that I can find? Sounds to me like they are built the same, specced the same, and are using similar marketing catch-phrases which all seem to say the same thing. Confused yet??
Bingo

That's because I'm losing some insulation!

Ron,
PM'd you.
