4x4 and towing

I have a 03 taco v6 automatic double cab with weight distribution hitch,brake controller ,sway bars and tranny cooler.I am going to be towing a travel trailer weighing approx.4000lb.Im new to the towing scene so should i tow in 4x4?Should i put it in low gear going down steep grades?Will i encounter any troubles towing 4000lb?Im i lil nervous and hoping i got everything in order b4 i attempt to tow.I will have to go through some steep mountains for about 45 mins .

 

I've never heard of towing in 4WD unless on uneven/slippery terrain. If you're on the highway, 2WD will do it.

It's wise to use engine braking to rduce reliance on the Taco's brakes. The brake controller works with a gyroscope inside that detects vehicle movement, so if the truck slows by using engine braking, the trailer brakes will come on.

 

Thanks for info,,,when you say wise to use engine braking im assuming your that it would be wise to put in low gear going down steep grade??

 

Yes, to stop the truck and trailer gathering speed.

 

I would not tow in 4wd unless it is to get started on slippery ground but once going on paved road 2wd should suffice. Only in the rice fields do we use 4wd to get going.

 

the only time i used 4wd when towing was to take a boat out of a steep dock. other than that, 2wd will do. Not to mention that driving in 4wd on dry pavement will ruin your diff

 

THE 4000 lb shouldnrt be a prob???????????
