I had a class III (5000lbs) on my Fronty and a weight distributing platform (this holds the ball) for my 23' TT and the weight dist. accessories were only rated for 5000 lbs.

SO, know you can't install a class III receiver on the truck and then later add the class IV weight distributing system (platform, chains, and steel rods) to get a full class IV system. You must change the receiver bolted to your truck to a class IV.

Hope this helps!

The Titan and Armada get class IV hitches. Frontier/Xterra get class III hitches.
