I had the solid fuel heater in my 1st Callen, ( full stand up headroom ). It loved a combination of 2"x2" oak & doug fir , with the odd kingsford briquette thrown in.
I have always used a smoke detector in my boats and campers.
Home Depot just had a sale on Kiddee smoke & CO detectors. I bought one for my current Callen shell and it works very well, set it off with errant smoke from the campfire wafting into the camper.
If you camp in wet weather, the dry heat of a solid fuel stove is awesome.
The diesel stoves do emit a diesel smell, the propane versions are really nice,
vented exhaust, little flame window for aesthetics.
What ever heater you choose, spend the $30 for a combo detector, and crack the windows / vents.
