I agree with everything you said here. Doing some looking around it looks like the new Smittybuilt winches have a good rating. Cable size & length is a big deal especially with DC current. Jumper cables won't do it. As I said earlier I started this because of a winch on a friend's trailer. Now I have a killer setup on my pickup and still none on my trailer. I like the idea of a separate battery & winch on the trailer so if I'm towing with another vehicle I still have a winch. Close short runs of big cable + a big battery would allow a smaller winch to roll something no the trailer. No need for a 12,000 lb winch. I need to check out my alternator and next time I replace my battery go for the most amps that will fit in the space.
