Can you install a tow package in a 2011 Tacoma if it was not installed at factory?

I have a trailer that the tow weight is 3800-4000 lbs. - my 2011 Tacoma is rated at 3400-3500 lbs. - Can I install a tow package? What parts are needed for the tow package? I called 2 dealerships and they thought I just wanted a trailer hitch installed. They didn't seem to know anything about it.

 

You need to go to RV place that they have tow accessories.. they discuss it with you on what you need and help you out.

You will need hitch, ball, brake controller, etc.

 

Towing package includes:

27F battery (non Tow Package has 24F)
130 Amp Alternator (non Tow Package has 100 Amp)
Engine Oil Cooler
Auxiliary Transmission Cooler (A/T only)
Class IV Receiver Hitch
7 Pin Trailer Connector with Trailer Brake Control Harness in Cab (Brake controller not included)
2012 and up models added Trailer Sway Control Programming in the VSC System


You can add most everything easily but it won't change the legal tow rating of your truck, if you get into an accident and you are over the tow rating of your truck you could be liable.
