Secondary Trans Cooler Question

We have a 2014 Forest River Sunseeker 3170DS Class C RV. We just got set up with a Readybrute system to tow our 2013 Jeep Wrangler Unlimited. We took our first trip with the toad 2 weeks ago from NJ to Vermont and the RV seemed to strain on the slightest uphill drive. My husband spoke to someone yesterday that mentioned he needed to add a secondary trans cooler to the RV in order to tow the Jeep. Can anyone else provide guidance? We do not want to damage the RV transmission, but are not sure what we really need to do.

What you have now with a tranny cooler should be adequate, if you're not exceeding the GCWR and even then, a little over shouldn't hurt, unless you're climbing the rockies all day long in extreme hot temperatures.
Having said that, you can't expect the rig to pull this weight without some straining and your best bet is to keep the rpm up into the hp and torque range, as you climb.
Besides, most modern transmissions have a heat sensor and will send the coach into limp mode if these internal temperatures are exceeded. Even then pulling over and confining your speed to 25mph in low gear will give you a 25% gain over the allowed GCVW, if that's the only factor under consideration and most likely is with what you have.
Now, I have to keep wondering with all the money that's wasted on junk by the manufactures, there isn't a tranny temp. gauge on a lot of these coaches and something else you might want to consider for your peace of mind and if for no other reason.
