Can A Jeep Grand Cherokee really pull one of these trailers...???

Hi folks, just joined the forum as I am REALLY interested in buying a 2620 SD. However, I have been doing some quick math and I am a little concerned the 5000 lb tow rating on my 2000 GC 4.0L I-6 4WD isn't all that it appears on the surface.

The Vehicles GCWR is 7550. Impressive enough. However when you subtract the base curb wt. of 3970, that only leaves 3580 to play with. It appears the 2620 SD has a dry wt. of 2865 and a load of 1210. That comes up to 4075, or potentially 105 lb violation of the Jeep GCWR.

That seemed surprising to me, in light of all the hype Trailmanor makes on how most cars can pull these.

Am I calculating this correctly? If so, I guessmy options would be to carefully limit my load. However that raises another question and that is whether the Jeep's base curb wt. is dry or if I need to factor gas, people and gear as part of that load allowance.

Love my Jeep and hope there is a solution here...
