Trailer winch question

i'm looking at winches for my trailer (other one broke). boat is 2,850 lbs dry.

Overtons has a 1,600 lb winch with a 3:5:1 "dual drive" and a single drive 1,800 lb with a 5:1 gear ratio.

it says the dual winch "uses two gears for an even load distribution to eliminate frame torque". don't know if this matters...?

which one do you think would be a better choice?

check out www.westmarine.com or www.boatersworld.com I'm sure you can find something between the 3 websites that will work for you

I bought the 2,000 lb Overtons "dual drive" winch, its a quality product.
