Leaf springs will ride stiff & bouncy when unloaded. But, a more fancy suspension can be a very big waste of time depending how you set it up.
Assuming you go with solid axles, you can do radius arms, but you'll need to build a track bar. You can do away with the track bar by running a wishbone 3-link or upper triangulated 4-link. Alternatively, you could go independent suspension with an dual A-arm/wishbone setup & individual axle stubs.
I looked at all that and it adds SIGNIFICANT cost. The suspension can easily become the most expensive part of the trailer. There's even a trailer build thread on JeepForum setup with an airbags + upper tri 4-link using adjustable Currie JJ control arms.
The question I ask with that is why? what are you accomplishing? It isn't suspension flex, because all the "flex" or articulation occurs at the hitch with the vehicle. Independent suspension on the trailer can be used to level the trailer on an uneven surface...or maybe you should just pick a better camping spot. The only other thing you'll gain in the trailer with fancy suspension is a better ride - but you're not personally riding in the trailer....so who's going to care?
