Follow the same towing guidelines as for the Isuzu Trooper RS which has the same wheelbase as the VX: 5000lbs tow and 500 tongue. I'm not certain why Isuzu chose not to include this in the VX manual and opted for the "towing not recommended" comment other than dealing with an overly-litiginous American society. But a survey of Isuzu's other 90-inch wheelbase vehicles will yield the same stats for the drivetrain. I regularly towed full loads with my 1993 Trooper RS and will all of my VX's too, you just have to be mindful of the short wheelbase.
