Hey johayes915, welcome to the forum. Not sure, but suspect you can tow at least 7000lbs with a V8 Durango. Shouldn't have any trouble with your trailer, as it is fairly light. Do you have a towing package on the Durango? If not, you will need a heavier frame mounted hitch and wiring harness/connection (Class IV). The bumper hitch that comes standard on most SUVs/trucks is not rated for towing much more than a super lightweight trailer. Happy camping.
