I pull a 3000 Lb trailer with the 90. For camping trips. I have even taken it on some long long trips. the short wheel base makes it a bit squirlly but you shouldn't have that problem. My book states 7000 Lb I would not advise that in fact us Dot only gives it a rating of 3500 lb. . I can see why. All this is based on a petrol d 90. Sorry but thats the only experience I have.
