As those were the three possible axle ratios Ford offered that year (not all with every engine), the VIN report isn't saying anything more than that the van has a rear axle. I suppose that's a good thing, even if I might have taken it for granted.
A class 1 hitch maxes out at 2000 pounds or less, and perhaps in this case would just be a hole in the bumper without a receiver or anything. You'd need a class III or IV hitch (assuming a previous owner hasn't added an aftermarket one). You'd also need a brake controller and a seven pin trailer connector wired in. None of that should be particularly hard or expensive to procure.
