tow vehicle

My wife and I are getting a new 3023TM in about eight weeks. I wanted to get input from owners about our tow vehicle. We have a Nissan Frontier with V-6 and auto transmission with a 5000lb tow rating. It has a class three hitch and we are going to get a WD hitch I'm also installing a heavy duty transmission coolant system. Does anybody think this would be a problem. The dealer said it wouldn't be but I like to get as many opinions as possible. Thank You for any input and I think this is a wonderfully informative message board.
