For your situation, I'd highkey skip the factory bars because they honestly have a weird curve that makes mounting a heavy box a total nightmare. I've done the technical math on the load ratings, and the Mopar ones are basically just for show once you load up for a family of five...

If you want zero whistle and max strength, it's really a showdown between Yakima and Thule.

Option A: The Thule WingBar Edge Roof Rack System is literally the gold standard for being quiet. It uses an aerodynamic shape that kills that annoying wind noise, but it’s gonna be your most expensive path at around 600 bucks.

Option B: Yakima JetStream Crossbars with the Yakima TimberLine Towers is my top pick for value vs performance. It fits those T&C side rails like a glove and can handle 165 lbs easily, which is perfect for a Thule Motion XT XXL Cargo Roof Box or a couple of heavy kayaks.

Honestly, I'd go with the Yakima setup. It's a bit more rugged for the price and doesnt flex when your hitting highway speeds with a full load!! gl!

Quick question - before I give advice on a specific setup, are you mostly concerned about the total weight capacity or just the security of the mounting kits? Safety is literally the most important thing here, especially since those factory rails on the T&C can be kinda flimsy if you don't use the right fit kits. Honestly, you gotta be careful because if the mounting isn't rock solid, heavy gear like kayaks can actually warp the rails or worse at highway speeds, right? Make sure to check if you're looking at something like the Rhino-Rack Vortex ROC25 Flush Roof Rack which is super sturdy, but yeah, just let me know how much weight you're actually planning to haul up there!

TL;DR: Avoid the Mopar factory bars if you're doing heavy loads like kayaks. They're cheap but they'll sag and howl at 70mph, which is a total vibe killer on long trips.

I've been driving T&Cs for over a decade and honestly, sticking with a solid aftermarket setup from a brand like Malone or even some of the heavy-duty Rhino-Rack kits is the way to go for budget-conscious builds. The big mistake people make is buying the cheap universal clamps from big box stores—they never sit right on those specific Chrysler side rails and can actually scratch the paint or, worse, slide around.

If you want to save some cash, definitely look for used kits on marketplace. I found my current crossbars for half price and they're solid as a rock. Just make sure the mounting feet are specifically rated for the van's rails, right? What's your actual budget for this? Cheers!

Basically, I've had way better luck with Yakima for heavy gear cuz the factory bars flex way too much. Are you planning on hauling heavy kayaks or just a lighter cargo box tho??
