Frequently, yes. Bed-mounted accessories are often sized or positioned around a specific bed length, and the same truck can ship with two or three of them. Check your configuration — short bed versus standard versus long — before ordering anything that spans the rails or mounts to the floor. The year, make, and model filter narrows it, but the listing's fitment notes settle it.

Thread locker on fasteners that don't need frequent removal, nylon-insert lock nuts where they do, and a re-torque after the first rough trip while everything settles. Rubber isolation helps wherever metal meets metal. Beyond hardware, listen: a new rattle is an accessory announcing its intention to leave. A five-minute bolt check after rough weekends catches nearly all of it.

No — it depends on the job. Metal wins where structure and clamping loads live, but quality polymers shrug off UV, don't corrode, weigh less, and don't buzz. The trouble comes from bad versions of either: pot-metal hinges and brittle bargain plastic fail the same way, just in different weather. Judge the design and hardware, not the material category, and let listed ratings break ties.

Static is what a part holds while parked; dynamic is what it's rated for in motion, and it's always the smaller number. Off-road adds impact multiplication on top — a pound bouncing through a rock garden pulls harder than a pound on the highway. Treat published ratings conservatively for trail use, and if a listing gives only one number, assume it's the flattering one and ask.

Usually a basic socket and hex set, a torque wrench if you're doing it right, and the patience to read instructions before drilling anything. Most small accessories use factory holes or clamp-on mounts, and listings flag the exceptions. The torque wrench is the underrated one — gorilla-tight strips small fasteners, and finger-loose feeds the washboard. Check each listing's install notes for anything beyond hand tools.
