Buddy Heater or Big Buddy Heater

[perch chacer]

Walmart has the buddy heater for under $50

Go for it.  Gives off a lot of heat. All you'll need for a 2-man flip-over or a small to mid-range hub.

I use the Big Buddy Heater for my Otter 3 man flip-over. However, the Buddy Heater is what I use for my 1 man flip over. Not so much an issue of weight, but of size. Hard to pass up a $50 Buddy Heater from Walmart.

I use the regular buddy heater for my big Otter XTH Resort hub shanty, and it heats it up very well.  It is an insulated shelter, so that helps a lot.  I bought a big buddy this year, but unfortunately didn't get a chance to use it.  I got that more for at night, the regular buddy seems to struggle a little bit more when it's frigid and the sun goes down.

That brings up a good point. There's a significant difference between heating a shack on a sunny day and at night. Even if it's cold outside, the sun alone will warm up the shack to a degree.
