Does anyone have a good idea how much my titan can reasonably tow? I have the tow package, hitch said 10k, truck is V8 and my trailer rv is dry weight at 7300#, is this reasonable? I have the additional electric braking and weight distort tow assembly as well. Seem like it labors. any thoughts? RV label says GVRt is 9000#. not sure what this means exactly and can't get answers. Thanks for your help.
