Best portable heater (30 amp) for my rv?
Would appreciate anyone who has a ceramic or other type portable heater to chime in and tell me what brand they have and if they feel it does a good job heating. My rig is a 32 feet Class C. thanks...

I’ve always preferred ceramic heaters for their safety advantage over most other portable electric heaters. The only other portable heater that would have a similar safety level (some would say better) would be oil-filled heaters. I would say the ceramics work better, and are much smaller though.
This is copied from the Wikipedia article on ceramic heaters. It briefly explains it better than I can.
“Electric heating elements made of resistance wire have a positive temperature coefficient of resistivity, but do not increase their resistance enough to be self-regulating; they are typically used with the wires red-hot. The ceramic, on the other hand, increases its resistance sharply at the Curie temperatures of the crystalline components, typically 120 degrees Celsius, and remains below 200 degrees Celsius, providing a significant safety advantage.“
Keep in mind also that air circulation is important, especially in an RV that typically isn’t insulated very well. If you allow the air to stratify inside the camper, you will find yourself needing to run the heat more, and possibly still having freeze-up problems with plumbing and tanks.
