Hey ya'll

Fairly new to the forum and I already need some help. Against my better judgement, my wife and I sold our 2003 Expy that we used to tow our 23 foot travel trailer. I am now trying to get my 2004 Explorer in shape for the job. It is equipped with the following...

4.6L V-8
Auto 4WD
3.55 rear

I know that I am well within my towing capacities, yet I do not have a trans-cooler and the truck only has the 1.5" reciever on the rear.

My question becomes this... where can I find a replacement hitch that would take the place of the factory installed item and how hard is it to install a trans-cooler on this vehicle? I am not looking for a hitch that "mounts below" the factory hitch but replaces it.

Any help would be greatly appreciated. The trailer is having some work done currently and I will be needing to pick it up in the near future.

Thanks,

RG
