talk about someone thats done his home work, im impressed, thanks for all that info, and yes i bought one of those for 50.oo and pulled a mini van up on my trailer, it got the job done but that was about it, i mounted a battery on the tonque of my trailer to hook my winch to then ran power from my rear outlet off the truck to keep the battery charged. it is funny how companys trick you in the desciption on items . i have notice how they talk about single line or double line. i will have to do a little more research on the one to buy, i would maybe use one a couple times a year. but if i had one i might find more reasons to use it. thanks again for your opinion.
