Ran mine to a simple 1.5" PVC T and then to each factory under dash vent. On 54's the dash trim spreads the warm air nicely and has saved me several times when it fogs up both in and out. The triple vent is almost too much for the tiny cab and the 2 vent may work better. Does heat and defrost better than all its multiple predecessors over the decades. Just the thought of some of the old boxes in winter still makes me shudder!
