We are narrowing down our trailer choices. The three we are looking at all have their manufacturer's version of an arctic package. Two of the three have 30 btu furnaces and one has an 18 btu. All t...

I have no real experience camping in sub-freezing temps (though I spent a lot of time in my RV in sub-freezing temps while swapping out the engine!) but...it's fun to speculate anyway.
I get the argument that a larger furnace will get the living area up to the set temp faster and then shut off. But I think the point pianotuna is making is that the storage areas (where tanks and pipes are) will cool faster than the living space. So, a smaller furnace running for a longer period of time will give off more constant radiant heat to those areas. At least that's how I interpreted it. Again, I have no real world experience but my fresh water and plumbing is all in areas that aren't directly heated by the furnaces, but since the ducts run through they warm those spaces. I kind of get the small furnace argument.
