Xtreme Heater Top View Xtreme, I received the heater today. Very impressive unit. For the initial test I am going to set it in the engine compartment overnight with out mounting it. Let you know how good it works. Rick – Looks like it worked great engine room stayed at 42 last night and it was 30 outside. Great product Great customer service I have been very happy with it’s performance and the way it saves a lot of $$’s versus it’s competitors
