So I'm thinking of asking for a winch for Christmas. I just want something reasonably priced might be useful in getting myself unstuck now and then...

Is this one powerful enough:

It will bolt right on to the Calmini bumper right, that bolt pattern is the standard correct?

Any winch suggestions?

I'd go with the Warn 8274 . It has plenty of pull for your truck (it pulls mine). It's fast and reliable, gear driven so the drum and wraps are cooler than the planetary types. It'll cost more than the Tabor, but well worth it. Don't know how it'll fit your bumper, Calmini should be able to tell ya.
