After seeing a Teardrop in the snow at Yellowstone in the summer.
Just me...but I think you are over thinking it, just how often are you planning on camping in those conditions....many of us have camped well into the 20's with no "onboard" heat and have been fine and it wasn't a summer thing...daily temps were only in the 40's. It was spring in the high desert of Nevada. It's camping!
Many of us just put a lantern in the tear prior to going to bed...have some decent bedding to account for the temps. The interior of mine was in the upper 40's in the morning and it snowed during the night. I was comfortable and I didn't have my dog with me to help heat it up. Kinda depends on your camping mate if you have one.
If you want heat and not deal with any of the elements....no matter what you do, it's gonna cost ya, dollars and time or get a larger RV. Whether it be a furnace, pet cool, blanket that may suck down a battery or whatever.... and if you are camping in a tear...and it's warm...are you gonna sit inside all day long?...get out and build a fire..it's camping!
