Any problems with a 2003 ford ranger edge 4x4?

I m looking at one with 160 thousand miles. It has a rebuilt transmission so that s already a plus. Its a v6 automatic though. I heard that the tranny for the v6 is better than the 4. I m also concerned that its a 4x4. Is that reliable in that vehicle? It seems to rum really well with tons of kick it d be an awesome truck for me to get started in as an electrician. Any tips, warning signs, things to look out for etc would be much appreciated. Thanks
