It's a major issue for us. We try to move to temps that would have us running the furnace a little and not running the AC at all. We can run the AC on a 3000 Honda on those days when the afternoon is a little hotter than expected. I'd rather need to run the furnace more but when it gets into the low 40's or 30's it's time to move on which is a combination of moving south and or adjusting elevation.
I never pull into a place in the dark and don't see a need to risk much wind when we have all the time in the world. I also try to never move in the rain.
Our target is to be in ideal weather while dirt biking in the best places in the country and as safely as possible. It's not always easy but we are committed to toughing it out.
