Holy negative NANCY!!! They get more than enough airflow, what are you talking about inefficient? (If you're referring to how the hot and cold side are next to each other I can somewhat agree, but on the other hand it's 32,000GVW!!!!! and was the best way to safely route the lines) And how does mounting a bar and plate take that much less time? Also why do I care about saving space somewhere nothing else will ever be placed?
