I love hearing how well your new T4R did on your trip because i just bought one yesterday after a long trip to the Carolina beaches ( i may have been one of those people struggling uphill as i had a LOADED silverado).
What kind of cargo carrier did you use on your trip (on top or hitch) and if on top (skybox style) how was the wind noise?
It's the Karrite Explorer (label says Explorer by Karrite - it's gray on the top and black on the bottom).
Here's an image:

I bought it about 12 years ago at Walmart. Wind noise is good (it's aerodynamic unlike other "box" top carriers). It was very cheap, and I would NOT recommend it. It's lasted for all those years, but my issue is it only opens from the side (there are two key locks on the right side, and "clamp locks" on the front and back end). When the sun is out, the plastic tends to get soft which causes the carrier to close when loading/unloading because it's somewhat melting where the front and back hinges are. And it's extremely terrible if you are installing it because that's when you absolutely need to have it stay open for a long time.
Installing it is a nightmare. Even when using a ladder, getting the two clamps on the hinge side is almost impossible to reach around to install. Again, if you're doing this in the hot sun, expect to have your arm pinched while trying to tighten the clamps. One year, I had my daughter go up on the roof inside the carrier to line them up for me to tighten the screws. But she's too big to go up there now.
Before I owned this one, I borrowed one from a friend. It's made by Sears (X-Cargo), and has a lock on the front and opens from front to back. It was very roomy, and I regret not paying the extra $ to buy that one before I found the Karrite. I never tried the Thule and I think Yakima makes some, but I would bet those are much nicer than the Karrite.
Lastly, I store all of our beach gear in the carrier. I fit four beach chairs (they are the Tommy Bahama ones from Costco -- which I would definitely recommend because they have pockets, headrest, and are made of aluminum so they don't rust), a beach umbrella, a "stroller type" cart with big wheels, sand toys/shovel, and fabric cooler that fits into the stroller. It's a tight squeeze but if you strategically place the items in, the lid covers just fine. This keeps all the sand in the carrier so all you need to do is dump it out after vacation.
BTW, have a great time on your trip!
