We are planning to take our stock trailer to Colorado to haul our UTV's in and then sleep in it at night. Want to see if anyone has ideas for heat or any other thoughts on doing this. Thinking of using one of the Buddy Heaters since it has a safety shut off on it. Also our openings have plexy glass covering them so we can slide open if need be to vent. Not sure we would even leave heat on at night anyway since we all have good sleeping bags rated to -20. Thanks
