I've now had 6 4 wheelers; 2 with 4wd. I've never really needed it. However, my Wife got stuck once while in 4wd. I had just gone through in 2wd with no problems. I guess it would be OK to have but I wouldn't pay extra for it. My land is very rocky, sandy and hilly. Now, it is pretty well washed out.
2 had winches that I only used to stretch fence wire.
Without a sense of urgency, nothing ever happens.
Boy, if I say "sic em", you'd better look for something to bite. Sam Shelley, Rancher Muleshoe Texas 1892-1985 RIP
