I recently bought and this last weekend used the Big Buddy heater in my Cabela's Alaskan Guide tent. I read in the instructions that it's not recommened to run it while sleeping, just incase it tips over So, I only turned it on right before bed time to warm up the tent before we went to sleep to change and after I woke up to change. My girlfriend said she wished we can run it all night. Just wondering if anyone does run it all night?
