I certainly would not bother. These things are made for what they do and already have oversized coolers. I put a transmission temp gauge (Scan Gauge) on my Freedom Elite and the temp never budged even in the high mountains of Colorado, Utah and Wyoming with their 80 mph speed limits. My Class A uses the same drive train, weighs more. is less aerodynamic and tows a Jeep. It includes a factory transmission temp gauge and it too has never budged past normal. If you’re worried about it buy the gauge and just keep an eye on it. The Scan Gauge just plugs into the port under the steering wheel. It can monitor all sorts of interesting things in addition to transmission temp. I’ll even think about selling you mine if you’re interested as I’m no using it anymore!
