Joe,
I split your post off into it's own topic. I think it'll get a lot more notice.
The
Biggar is a really cool trailer. It would be worth buying the trailer and having to get another tow if yours won't do it!
Check your owner's manual. You need three numbers. The gross vehicle
weight rating, the gross combined vehicle
weight rating, and the maximum hitch
weight. If your Biggar falls under all of those for your Dodge, then you're good to go. If any of them are outside the parameters of the van, you're better off looking for a new tow rig.
That will at least get you started!
