Hi Dan,
I hope to be building a small "tiny house" on wheels in the next few years myself...and have given designing it a lot of thought. I love
RMH, and look forward to what others think, yet in my "rough numbers" it's a "no go," just because of that M part of
RMH. Even if you plan on moving it once a year at most, the mass part just doesn't help. On the other hand...perhaps a Micro RMH will work as these small houses heat up really quick. Even a "shepherd stove" size RMH with soapstone augmentation would work...I am still figuring this out myself. So far it is a white cedar timber frame double wall with infill system for installation.
Regards,
j
