Unfortunately most of those standard tongue jacks aren't sturdy enough to allow you to push the trailer around 180 degrees on soft or rutted ground. I've found that they are fine on hard surfaces and ok on hard-packed gravel, but otherwise they are hopeless. If you are stuck on a really tight trail, a tongue jack probably won't help you anyway.
If you really want to do this, buy the heaviest folding tongue jack you can find, with the largest diameter shaft, and make a set of double _castored_ oversized "floation" wheels that you can install for the rare times you have to do this off road. The rest of the time the wheels can ride in storage (maybe on your roof rack, if you have one) and your regular small wheel can be installed.
It's usually better to maneuver the trailer by "jack-knifing" it (turning it 90 + degrees to the truck), disconnecting, moving the tow vehicle and reconnecting. Usually you can do a complete U turn in one operation, but it might take two. It is SO much easier to push the trailer around using a truck than by hand.
A telescoping tongue "may" make this easier, depending on how far around you can get your trailer now. If you extend the tongue it will let you go way past 90 degrees, which makes the next step easy. Unfortunately a longer tongue also requires more trail room to swing the trailer. It's best to keep the tongue as short as possible while still letting the trailer go past 90 degrees. If you want information on how to make a telescoping tongue, search here or ask. There are some of us who have done this mod.
BTW nice trailer! Do you have more pics? Do you ever go to North Africa? If you can give us some more detailed information we might be able to help more. And we really do want to see your trailer
