I also have a Big Buddy. It is nice, but I would caution all to never use it while sleeping. It is good to know that the CO output is negligible, but it is just not worth the risk of waking up dead if it did have a malfunction and started pumping out CO.
Cracking open a low window and a slightly opened ceiling vent at the opposite end of the trailer is a good practice when using one of these appliances.
Also, if you have pets, you need to be vigilant that you do not get a flaming or smoldering fur-ball running around in the 5er, some kind of metal screen around the unit would be advisable to protect from accidental burns. Most pets are pretty smart about hot surfaces, but a wagging tail on an excited dog goes every which way, .....the smell of burnt hair is not very appealing!
