need opinions please tow truck

good evening everyone, we have been getting more and more cars 2 this week so far. i have an extra truck dodge 2500 cummins 5 speed long bed there is a cl add in my area for a holmes 480 bed. i am very mechanical inclined but have never operated a tow truck we use a 18ft car hauler with a 8000 warn winch and a 16 utility witha 2000 winch now. i know i will be able to get in tighter places the add says it has two winches wondering what the 2nd is for, and also any extra uses any of you have come across other than towing vehicles. in reality we are getting by just fine now but just curious to all the advantages. plus is this even a good deal????? thanks very much in advance cory couch
