infiniti qx56 as tow vehicle. with a 10K 30 foot trailer

I just went over to look at one of my neighbors new trailer , a 30 ft 10k lb bunkhouse , he got a good deal. So I looked around and asked , What do you tow it with ? He points to his infiniti qx56 . I look at him and ask if he was kidding . He wasnt . He tells me its rated to tow 8000 lbs . And he shows me where it says the trailer is 7900 lbs on the side plate . So I ask him , Are you going to bring clothes ,food , propane or anything in the camper ? You only have 100 lbs left . He has this puzzled look on his face . I showed him that was the empty weight and once he loads it with stuff he will be close to 9500 lbs .

So he tells me its got 400 hp and it doesnt tow " that bad"

I basically told him its a major accident waiting to happen , not if , but when . And when you throw 5 people in the vehicle you are even more overloaded . With that short wheelbase WHEN it starts to wiggle your done , that 30 foot trailer will wag the dog and its over .
