It may be that it worked for you. BUT the warning on the box tells you NOT to use it indoors. There's gotta be a reason for that.
That's actually not true. I don't know which version you have but the box mine came in says "indoor safe". In fact here is part of the description that is on Cabela's website.
"
Portable Big Buddy Heater is ideal for taking the chill off almost any place you need extra warmth. And because it's equipped with a low-oxygen shut-off pilot safety, it can be used safely in tents, blinds, ice shacks and other enclosed areas. "

Possibly you have an older one?
Anyway I love mine when I'm tenting it. I also use the 20 lb bottle and it works great, too easy not touse like somone else said. I do keep the propane bottle outside the tent and run a hose inside.
