Did you go with a RF brake controller? I did and it works great. As you stated towing any TT without a truck is open for many opinions (I have also towed with a truck). I decided to tow with my DJ after doing some research. This is what I found...from what I researched the structure of the vehicle did not change from 2010, which had a GCWR of 8300 lbs, so I don't think the reduction in tow cap has anything to do with body structure. As mentioned the Caravan with same engine and trans combo with exact shift pattern is rated for 3600 lbs with the only addition being an auto level rear suspension, nothing else, so I don't think it has anything to do with engine and trans. Also my DJ crew has a trans cooler, found the part number on it and looked it up. The only other change was the rear suspension which may account for the reduction as mentioned in my last post. Also, with seven passengers and their luggage you could be close to rear GAWR as well as the GVWR, so that leaves no room for added tonque weight, Dodge needed to take this into account as well. As far as being safe there are a few 4000 lbs vehicles rated to tow 5000 lbs. I feel safer knowing my tow vehicle weighs 1000 lbs more than my trailer rather than rely on a manufacture rating their vehicle to tow a trailer that's a 1000 lbs more than their vehicle. Just keep an eye on all temps, and pay attention to shifting, as you should no matter what you tow with. Happy camping!
