5rv with the highest R factors

I traded a Hitchhiker for a Big Country and the difference in insulation is dramatic. Big Country is much more comfortable in both hot and cold weather.

Our Heartland Landmark has stayed quite comfortable down to -6 degrees, with nothing freezing inside or out. Spent quite a few days this past January in temps from just above freezing to just below...insulation and cold weather prep worked great.

The Heartland is a good choice. As stated elsewhere in this thread, just stating R values doesn't mean a whole lot sometimes. Heartland does test in the Dometic Extreme temperature testing chamber, and they pass the cold testing, as well as the heat testing. From personal experience in my Heartland XLT, it is easy enough to keep it cool in 90+ degree heat. It will be in storage for the winter months, so I won't personally conduct my own cold weather testing. However, it stands to reason that if it can be kept cool during the summer, it should hold it's own in the colder weather.

Check out Lifestyle RV. I was in a campground in Las Vegas about three weeks ago. Full sun. No shade trees. No grass, only Asphalt and gravel. Outside temp was 117. I had both a/c going with ceiling fan. Kitchen/living area 78 max. bedroom 76 max. I was impressed.

Dutchman Denali had some good R values when we looked at them while back.

Maybe it wasn't certified, or maybe it was reflective foil, I don't know. Numbers just seemed good.

Good luck.

We had a 2012 Cameo and now a 2013 HitchHiker Champagne. We are summered the same place as last year and I can tell you the Champagne is a lot easier to cool than the Cameo and is 2' longer and a wide body.
I would suspect the same story for winter use.

If we had not gone with the Champagne, my next choice would have been a DRV.

Check out Lifestyle RVs.
I was in a campground three weeks ago, in Las Vegas, full sun, no shade trees, no grass just asphalt and gravel. Outside temp gauge was 117. Both a/c running with ceiling fan. Max temp in main living area got to 78. max temp in bedroom/bath 76.

I was impressed.

An RV can have an R factor of insulation of 100, but if it leaks air like a sieve, what's the point ? My DRV has great insulation, but if I don't plug the 1/2 to 3/4 inch gap along the bottom of the kitchen slide, I might as well just leave the door open. The point is, look at more than just the R factor.

Our drv is better insulated than our newmar.

DRV just the insulation R factors NOT values of the assembly. Those would be higher.

Floors R29

Walls R16

How about someone posting actual insulation R values not what they dream up. Above are actual values of the insulation installed in DRV's.

Are DRV's R values independently verified? By whom?

Ok, the R values I listed are certified by the insulation manufacturer. NOT DRV.

Anyone can claim a wall for example has a certain R value as an assembly that is NOT what I listed.
