This is absolute hogwash. There is no way a Ford E series chassis air conditioner has the cooling capability of a 13,500 btu roof air conditioner. That is absurd on the face of it.
Below are just four (4) links talking about the BTU cooling capacity of vehicle cab air conditioning systems ... and a search yields many more articles that reinforce what these links are saying.
The information in the links confirms what I have experienced ... our motorhome's (and our sedan's and our pickup truck's) cab air conditioning systems have terrific BTU capacities (well beyond 13.5K BTUs at typical traveling engine RPMs). Our motorhome's E450 cab air conditioning system is easily capable of cooling our entire Class C when traveling at highway speeds in scorching temperatures - especially using it's MAX AC setting such that the interior air is only recirculated - instead of the cab air conditioning system having to constantly cool new hot air coming in from the outside.
