Thanks everyone. I will check out the links to find the one that is hidden the most and will do the job. We had one of those ugly low hanging/dragging U-haul
hitch on our last Sienna and I swore I'd never do that again, lol. As far as limiting my tow capacity, since I only have 3500 lbs for my van anyway the Class II does fit that limit. If I had a higher tow capacity I'd definately get the Class III.
Brian, is the hitch on your van factory or aftermarket? I'm curios since you said your crossbar is completely hidden and that is what I'm trying to accomplish as well.
