Kind of ironic to expect no clanking when a trailer is involved.
I absolutely despise anything rattling around on a trailer or making a bunch of racket. That one was one of the objectives when I built my utility trailer. And I'll promise you it makes no such noise. Not the fenders flapping, the ramps banging, gates, none of it. It's a pretty solid build. I built it almost ten years ago, and have dragged it to the east west coast, all the way to the west and back. Probably 20k miles total, if I had to guess.
I used an aluminum, diamond-plate box from TSC, and mounted it on the tongue, and it's been on there for every mile, since day one. But... I built the mounts for that too, so it's sits securely and well-supported, Inside are all the standard items you'd find in just about anyone's well-prepared trailer; plenty of ratchet straps, some slings, the truck hitch, replacement pins and misc. hardware, zip-ties, tape, a multi-screwdriver, utility knife, a couple spare padlocks, tire chocks, spare LED bulbs, WD40, hand cleaner, paper towels, gloves, wet-wipes, a couple towels, gallon of water, and a bunch of other "what-if" stuff. But all of those items are secured in two totes inside the box, so those items aren't flopping around while you're going down the road and gouging the bottom of the box.
My point is, it's VERY possible to have a trailer with everything you need, that's prepared properly, and does NOT rattle and clank, making a bunch of noise.
