For Montana van, hitch details are:

See Part number: 87410
Note:
- Class 2 style hitches have a 3500 lbs. gross trailer towing weight and 350 lbs. tongue weight unless noted otherwise.
- Class 3 style hitches have a 3500 lbs. gross trailer towing weight and 500 lbs. tongue weight unless noted otherwise.
For me, If I'm going to buy a Class II hitch, I'd rather spend a few more minor dollars and get a "much stronger" Class III hitch instead. Works for me...
