Negative Positive
Title: I 2nd the other opinions
Review: I'm nomadic and a cold wuss. Last winter (2010) I was camped near the Ojito wilderness in Northern New Mexico when the temps dropped to minus 12 fahrenheit. The Brinkmann (double consonants rool, maaan!) helped, but I had to augment it with the van's heater. It works great down to about 20 and keeps my summer R.V., a 1999 Chevy Metro hatchback (53 mpg) toasty. It IS a tad noisy, but, as suggested in another review, this may be inherent. I recommend it with a cautionary note: it's not in the league of the infernos of Burning Man.
Is the review positive or negative?
