Cute, but, IMHO, of somewhat limited value in a FGRV.
+ Points:
Looks neat, like a mini fireplace
Will cook you out of the rig in short order
- Points
Requires a significant amount of dedicated space
Manual
lighting with no automatic operation at night
Requires a big hole for a hot vent pipe
Heat output is 5,500 - 7,500 BTU, a lot for a small RV.
Expensive.....
