I have used a Buddy Heater for years in the back of my truck and run it all night. The key is I keep three windows open an inch or so for cross ventilation. I will be add a CO detector this year.
Same as the AT heater, $725.00 base price.
The $1,781 Adventure Trailer price is, well, just a little steep. Seven hundred dollars, about the going price for a good 110V/12VDC fridge/freezer, seems about right. We've been trying to find some of the discontinued Zodi tent heaters, and I've even contacted the Zodi to see if they would consider making a special run of these.
Very tempting if I decide winter camping is my thing!
There is this also:I just talked to a guy at Zodi and he said they are planning on releasing the new model in mid March. 3wks to late for my camping trip.
And I found this thread writtin 2009, where a poster said the heaters were in "redesign" for three years prior. That would put the date around 2006...
Me and my son used our little buddy at 9,500ft with no problems 2 weeks ago. Having on med in the lower annex made for a great nights sleep.I've used Big and Little Buddy heaters for years in both RVs and tents. They do have a low oxygen shutoff, which makes them unusable over 7,000' so to an extent they are "safe". To a point, but I'd not be comfortable running them all night.
We use really good sleeping bags, rated for much lower than the expected low temp. In the Rv when we start getting up in the Am run the Buddy heater in the RV just till it gets to say 50*. Colerman makes some nice inexpensive, little catalytic heaters which might serve you well and give you the chance to develop your own system. BUT, GET GOOD SLEEPING BAGS!
