New to the show, just had to throw my new trailer in the mix Just came back from a shake down trip to DV. Aired down she ran sweet...it was awesome getting way back in the boonies, on some pretty sporty trails and taking everything I wanted / needed including plenty of firewood and keeping my Jeep interior reserved for off road gear.
For me a trailer made sense, built it myself and cost less than a darn roof rack...those things are pricey! Trailer is very light, but built tough with a beefy frame and axle that I can drag over rocks...I don't even know its back there heading down the road. I put a 2" receiver on the back of the trailer and can mount a standard car hitch rack if more storage is needed (or a bike rack). One mistake is the wheel lug pattern does not match the rig, so I have to carry a trailer spare (laying flat inside the trailer). Also, I dig the T&G wood siding, but not a good choice for a wet climate as the T&G seams did not seal completely. I live in SoCal so this was not a big deal, along with a lid as this just adds more weight and prevents loading gear above the rim.
Kept the cost down with refurbished junk yard rims ($20 / ea) and used tires with plenty of tread from a tire store ($30 / ea). A RTT would be an awesome addition, but that will need to wait a while.
