Mount it on the side of the trailer and pull through a clevis hook and pulley at the front it will almost double the power of the winch. I use a el cheapo harbor freight winch that is portable...mounts on a quick release plate and it pulls my 3100 lb car up on my trailer just fine...it is a little slow but it does not get hot (knock on wood) But I only use it to load up at home cause The car lives at my fathers house and he lives in a housing addition and does not like me to run it any more than needed due to noise and upsetting neighbors.
