I'm going to be towing a car/trailer combination that's going to put me just a little over the 3500lb weight limit (3850) so I want to add an oil cooler and a transmission cooler to be safe. Etrailer.com recommended I buy the "Derale Transmission Coolers,Engine Cooler - D15902". I looked this up online and the only mention I can find of it is in...tah dah...etrailer.com .
Has anyone here used this on their Tacoma (or other trucks for that matter), if so do you recommend it and if not, what other combination would you recommend.
Thanks in advance for your thoughts/advice.
By the way I have a dealer installed hitch and I've had an electric brake controller installed.
The trailer I'm going to be pulling is an 18' version of this (with an MGTC, not a Lotus, inside):
