Mr buddy has some altitude limits that the Wave doesn't. Depends on where you camp, I bought a MB but returned it because of this. Much of my camping is high, 9, 10, 11,000', not this time of year
From their manual:
• When operating the heater at altitudes over 7,000 FT.
above sea level, the unit may not burn as bright as in
lower altitudes. This is normal. At higher altitudes, the
heater may shut-off. If this happens, provide fresh air,
wait 5 minutes and re-light. Due to local atmospheric
conditions heater may not re-light.
On a related note -- and relating to using the Wave at higher altitude:
Last month when I was camped at 11,000 feet in the White Mts I wondered if I should have vents open wider than when running my Wave 6 at lower elevations.
Seems like the answer is "Yes!". The settings on the heater feed in a fixed amount of propane at any altitude, and for complete combustion the same amount of oxygen would be required at any altitude. But at higher altitudes there is less oxygen because there is less air (the atmospheric pressure is lower).
For example, at 10,000 feet the atmospheric pressure is only 2/3 of what it is at sea level...so to get a fixed amount of oxygen (that is, fixed number of "moles") to the heater, 50% more air volume is required.
So, I'm not sure how to ensure that 50% more air is vented through the camper...but I know that it means that the vents need to be open wider. Yeah, there's not a huge difference between, say 5000 ft and 10,000 (about 20%), but it still could be significant if you were already on the border-line wrt venting.
Something to consider, seems like.
