You won't catch me singing anywhere in public but we could do a conversational test. I also would like to hear the difference.
Sue, the R values are the same if I recall the numbers correctly. Ours is relatively quiet but we do hear conversations going on next to our rig, etc. At least we hear that a conversation is going on even though we can't make out the words all the time. By the way, inside conversations can sometimes be heard by someone closeby outside, too. Have to be careful about that.
See another Montana or Mountaineer on the road? Flash lights twice, it might be one of us!
