Thanks for all the input so far. I bought an "exchange" tank yesterday and found it to be lighter than my others. I suspect they are overfilled. I also decided to check the flame sensor/igniter (one in the same in this unit) and found the entire enclosue smashed and out of shape. It looks like the trailer assembly people dropped it on the corner. The dealer should have caught this while investigating my complaints about the reefer. Without posting a picture I cannot fully explain how the "critical" placement of the burner and sensor is out of place. I still suspect oil in the line at the flame nozzle. I'm pulling the metal parts out today, reshaping them as they were at some point, and cleaning out the nozzle. The manual says alcohol is OK. They specifically say not to use compressed air (ruby nozzle can be blown out) or any probing (nozzle breakage). I will update my findings. I'm ready to drop the entire rig off at the dealer and walk away after so many issues
. Forest River has promised to send brakes, a galley faucet, and a cabinet door to replace the broken parts as well as reimburse for tires (we shall see).
