I'd second the utility trailer but you can go bigger, but not much bigger, if you go with an aluminum framed trailer instead of steel. Many states have a 3000lb limit before you need trailer brakes so the manufacturers all build their single axle trailers to 2990-2999lbs and use a 3500b axle, buying an aluminum trailer will buy you about 200lbs of cargo and still keep you "legal" at 3k. T4R tows 5k but it'll tow 3k way better for long trips. You can add shelves, hammocks, beds, fold flat tables, windows (mandatory if you want to sleep in it), and whatever else you can build. I prefer a ramp back door over barn doors. Check out stealth trailers., everything can be taken apart or reinforced with a square #2 bit, comes with LEDs, and you can add insulation in an afternoon.
Off road trailers will run you at least triple but will be more 4x4 capable if you really plan to go beyond fire roads and light off roading. You can always add a multi axis hitch or pintle hook if you want to get fancy. Buy a bigger set of tires and call it good.
