I would think that that info would be in your owners manual, ifnot someone at the dealership should be able to tell you. Another thing to keep in mind is the rating of the reciever and hitch you use, most factory class IIIrecievers (that I have seen)are rated at 4000#s dead weight and 10000#s if using a weight distributing hitch, which can make a differnce on how you tow. my dad found this outwhen he went topick up a '721500 (which weights all most 3.5 tons)that my grandfather was giving to my younger brother. He drove from Ca to Mo with his flat bed rated at 10 tons with a dead weight hitch, well when he got there and relized how heavy both the trailer and the truckwere together, hehad to go buy a weight distbuting hitch which cost $$$, just to get home. Any way back to your problem, if you are going to just pull or use a front wheel dolly you should be fine. If you are planning to put the charger on aflat bed you may need to check the rating on your reciever. Oh, and if you plan to tow a flat bed you may need to install a trailer brake, just a heads up.
