We have not been anywhere to push the limits like some of you folks. I don't know what our limits would really be. There is a difference between having to and wanting to. We have become extremely spoiled. All three four wheel vehicles we have, have heated seats. And we use the heat feature, even if it is only chilly outside. But heck, I use the heat feature in the lazyboy chair too. I think if my bed had that feature, I'd use it too. Jamey and I rode around 300 miles on Sunday, we both had on our underarmor, fleece under the leather and the turtle fur neck wraps. We were pretty comfortable, temps were in the high 30s when we left home, warmed up to the mid 60s in the afternoon then dropped back down to the low 40s. Jamey runs a little cold most times anyway, but he was chilly to touch, hands, face, body, but I had the benefit of heated grips, and I was down right warm, everywhere. We had no other electric on. We own it, just were not using it.
