Broke one of my own "principles" yesterday........
2500 lb wont pull a stuck egg off a plate,i wouldnt go any less than 4000 if you want to pull anything substantial. Lessens the bs factor too. Theres battery cable connectors that quick cable has. They are slick. 15 apiece,but can be found cheaper if you have the time. I have a few sets to go on my truck. Front back and one in the box,one on the boost cables and one on my inverter. Winch doesent need, its mounted between rear frame rails, pulls full size trucks onto my trailer with ease. Set it up to use 100 foot extension cord so its easy for 1 person.
