Use a weight distribution hitch or not?

I notice that your tow vehicle is a Dodge Caravan. Am I correct that this is front wheel drive? If that is the case, you surely don't want anything that is going to shift the weight to the rear. That will effect your steering. I'm surprised that you haven't already had people suggest a different tow vehicle....mini-vans are considered great people movers, but not great tow vehicles. Strongly suggest you check the weights for your specific van - they should be on a sticker near the driver's side door. Otherwise, give your dealer the VIN# and ask them for the information. Also, check the TRUE weight on the trailer, not the dry weight. That will also be on the trailer and be listed as GVWR. You may or may not already have a weight problem. Hope not. Yes, a WDH is heavy, but you may find it necessary to keep those front wheels where they should be instead of just skimming the road. Check these numbers and if it doesn't make sense, please come back, share the info and I'm sure there will be others with info that may help you.
