We have a 6 cyl 1996 4-runner. It has what appears to be a rather limited tow package with a frame mounted hitch receiver. Some forums I've read say that this package does not have either upgraded radiator for water or transmission. We're planning to tow a fairly small camper - weight approx 3100 lbs (wet and loaded) with a tongue weight of
310 to 450 lbs. The following additions appear to be recommended: proportional brake controllers, additional transmission cooler, and rear air bags. We will be doing a fair amount of driving on pretty rough and mountainous roads. What do you all think about these add ons? Are the needed, advisable. Any thing else we should consider.

Thanks

I highly advise getting a trans cooler. I think everyone with an auto should have one even if you don't tow but especially if you do. I did have problems running a trans cooler without a thermostat, but I was using a very big cooler.

I'd also suggest a synthetic trans fluid. I've had good luck with Amsoil ATF in a 3.4/auto truck.

I also think air bags are a very good idea. Another 450 pounds tongue weight will probably sag the rear end a bit. That really upsets handling and makes your headlights point to the sky. Also, make sure the rest of your suspension is in good shape. Shocks, steering rack bushings, sway bar bushings etc etc.

And a Tundra brake upgrade couldn't hurt. That's a cheap mod for increased brake performance, especially if you don't have the bigger 4runner brakes.

One small bit of advice, carry a spare tire for the trailer. Can't tell you how many times I've seen a trailer on the side of the road with a flat and the owner is off somewhere trying to find a tire while all his stuff is by the roadside unattended.
