While my vote is still for a tandem axle, one thing I would strongly suggest getting is Dexter Torsion axles. Rubber ride, independent of each other, better/smoother ride, no maintenance required. Side note if you will. My 4 place V-nose snowmobile trailer is tandem axle w/ said Dexter axles. Only 3 sleds in trailer and trailer is something like 30' long ball to tail. 2 sleds in front, 1 in rear. When traveling locally, I just drive them on, set parking brake and shut the door. Sleds do not move. I know folks will call me out about not tying them down, but that's another day as that's not my point for this thread. Point is, the tandem torsion axles are great and offer a great value to contents. Recently DW and I went on a trip that was about 300 miles from the house. For this, I did strap the sleds down, but watching the trailer, it was like watching a Caddy/Lincoln Town Car as it hardly bounced or swayed (ANOTHER POINT for Tandem axles).
True story^, and my sleds don't bounce around either. Couple of them that roll freely do slide a little sometimes, presuming steep slopes or hitting the brakes. It does ride good with only 3 machines (light ones, mountain sleds and a snowbike). It still bounces when empty.
BUT it doesn't ride nice with only 1500lbs in it because it's a tandem or torsion. It rides nice because the it has 3500lb axles and the empty trailer alone weighs 4k, so doesn't take much load to work the suspension.
However, this story, your story and 12Vs pictures have absolutely nothing to do with the OP's query.
First, he hasn't been back to even guesstimate how much he's hauling and second, he is talking a 12' little cargo trailer for "crafts."
There's about a 99% chance that what he's doing is exactly what 2,999lb rated single axle 6' wide cargo trailers are meant for.
Unless he's loading it heavy, there is zero benefit of a tandem on such a small trailer, but several downsides. The 2 biggest downsides are cost and the ensuing rough ride when there's 7klbs worth of axles and springs under a lightly loaded lightweight cargo trailer.
Lesser disadvantages are, the inability to move it around by hand, which is much easier with a single axle and buying 4 tires instead of 2, when only 2 are needed and slightly less fuel mileage.
