are hybrid trailers cold in winter?

We got a cordless space heater for our MyPod. We're planning on camping all through winter so that was the best option in the MyPod.

I'm good to about 15 degrees. My wife, about 50 degrees, so it is relative what "cold" is.

Beating the dead horse, yes, pre heat your heated mattresses, using comforters/thick blankets.

When we had a pop-up we learned to use cardboard under the mattress and around the bed ends. Cut it to fit and stand it up on edge. It was a lot warmer than canvas. Stored it under the mattress when not in use.

When we had our hybrid we also had heated mattresses never a problem Tom

from the OPs statement "I don't do well in the cold," I assumed (yep I know what that means) that he didn't want a discussion on arctic camping. rolling out of a cold sleeping bag into a cold area seems to turn him off.

You live in Texas, how cold can it get while you're camping?

We were fine down to the 30's, below that we needed to go with a heavy down comforter. No problems from cold from below, just around the tenting. And yes, we used PUG's and Reflectix.

When it is supposed to be cold we went with electric sites and brought a small electric heater.

Mummy bag, gizmos, no water and I'll camp to -15f.

We often camp in the "shoulder season" (spring and fall) and routinely have temps in the 30's. Just this past weekend it got down to 34 degrees F and was snowing. On top of that, it never got above 50 degrees all weekend, and cloudy. Our AC unit has an option for a heater plug, which we run in colder temps, and at times supplement it with a small electric heater. We stay nice and cozy warm. We never use the furnace, nor do we use any special mattress pads or tend end covers.

Again, I will mention that it depends on what you think is cold.
We try and go out for 1 last weekend in October before I need to winterize. Nights could be about 3-4 C, 35-38F with the potential for frost. I run 2 electric heaters and set the furnace at about 65F. The furnace might cycle a few times. Of course to keep condensation manageable, we crack some windows and leave the tent ends unzipped a little. Use PUGS and Reflectix in the tent ends. When we go to bed, the sleeping bag does feel cold, but it warms up quick. We use a queen size 10C rated sleeping bag. Maybe a mohair blanket on top. Usually by morning I feel hot as the hybrid doesn't really get that cold. Suggest putting some carpet on the floor to keep your feet from feeling the cold from underneath.

Then again, my son is in Scouts and they have winter camped to -10C in a tent. Nice mummy bag and sleeping on a thermarest ground pad, sleeping toque and warm pj's and all is good.

Just need the right equipment for the right job.

yes, more so than a hard sided rV.
