In quite cool weather, we sometimes use a rather large, flat 110v quiet radiator heater that has 1 degree digital adjustments and a remote. It is possible to adjust it to perfection from anywhere within, even inside our 30' trailer camper, including bed. No device surface ever gets too hot to touch. Finally, a single lo-temp-rated opened sleeping bag also makes a toasty extra top quilt in cold weather without disturbing our normal bedding.
For a fan we use the same O2Cool fan shown earlier.

Even when we boondock, this fan works great as a battery powered unit, indoors or out in hot weather. I think it runs for 18 hours on D cells, or nearly indefinately on the camper 12v system with a custom adapter. If you buy one, make sure it includes a 110vac/12vdc power supply as I have also seen them offered as battery-only with no power adapters.
When we did camp with our past TC, a great addition was a sheet of styrofoam under the mattress, and I do prefer an electric blanket in mildly cool weather while my DW leaves her side off. One advantage to an evenly heated electric blanket over a heated pad, is that the blanket never develops trapped hot spots where one is lying.
I hope to talk DW into another TC soon... for traveling.
