No easy way, I have a tent that goes on bed of my truck. Close the windows you get soaked with condensation. Open enough zip windows and you freeze. I have the Mr. Buddy heater that works somewhat but Iím afraid it will start a fire while I sleep or deplete my O2 level. Usually warm up tent, turn it off, start it back in morning. I use an air mattress, mattress cover, and a LL Bean 4 season bag. For me, condensation is a bigger problem than heat.
