Not sure about the gloom and doom comments about minivans. I've towed heavier popups (as well as other assorted trailers) with 4 bikes on a tongue-mounted bike rack for over 15 years with different vans with no issues. Setup is key. With our family situation, we need the flexibility of vans (seating arrangements, secure cargo storage, 1200-1400 lb payload, easy to park, fits in the garage) rather than the limitations of a full size crew cab pickup of which I have owned a few. I'll get another pickup in a few years after the kids are gone, but not now. I'm not afraid of using WD on a unibody, especially since the owner's manual is OK with it. I did not have factory tow packages on my vans, but added the necessary components. My Ford had various warranty issues back in the day, and the dealer never gave me any problems. No issues at all with the Dodge. The low center of gravity is a big plus on having a stable platform. But, I also know I'm not going to convince anyone else since most people think bigger is always better.
Just my opinion......
