DIY Diesel Heater Setup for Sienna Minivan - Tested in a Blizzard

Testing my portable diesel heater in a blizzard (27°F and 10" of snow) to see if my new Magnetic Quick-Connect system can handle the cold. The "Mistake" Report: It took 2 hours to hit 70°F because I made 3 big errors: No Insulation: I forgot my Reflectix window covers! Low Power: Didn't realize my app updated—I was only at Level 6 (60% power). Exhaust Fail: I melted the snow and scorched the grass. Efficiency Hack: In the garage, I’m hitting 147°F at the vent. What temperature is your heater reaching? Post your numbers and setup in the comments!
