Best accessories for Land Rover Defender off-road adventures?

What accessories have made the biggest real-world difference for your Land Rover Defender on off-road adventures, and which ones turned out to be unnecessary weight or expense?

Ive had a 2021 Defender 110 for about two years and Im comfortable with the basics like using the terrain response modes, airing down the tires, picking lines, and not trying to drive through things that are obviously too deep. Ive mainly used it for weekend trips around Colorado and Utah, nothing extreme yet, but Im planning a longer desert and mountain trip this fall with a couple of friends. That’s where I realized my current setup is pretty limited.

Right now its basically stock suspension, factory recovery points, all-terrain tires, a basic compressor, traction boards, and a small recovery kit. The tires have been fine so far, although I did get stuck in loose sand once and wished Id had a better way to manage tire pressure. I also carry a hitch-mounted recovery shackle, but Im not completely sure whether thats the best recovery setup for the Defender or if I should install proper front and rear recovery points.

My budget is around $2,000 to $3,500 over the next few months, so Im trying not to buy every shiny overlanding accessory I see online. Im considering a winch, rock sliders, underbody protection, a roof rack or awning, better lighting, and maybe a small fridge, but Im concerned about adding too much weight and hurting fuel economy or handling. Ive also read mixed opinions about winches on Defenders because of the mounting and electrical requirements.

For people who actually use their Defenders off-road, what would you prioritize first? Are rock sliders and skid plates essential on the 110, or are they mainly for more technical trails? Would you spend the money on a winch, or focus on recovery boards, a second compressor, and better recovery gear? Im looking for a practical setup for remote trails and camping, not a show build, and real-world brand or product recommendations would be great...
