It also appears to be a leading axle ? The little arm is facing the tounge of the trailer. The custom order form on redneck trailer has me a bit confounded.
Dexter is known for having a helpful sales staff. They will also take and run the "non-standard" request past their engineers to make sure they can build it.
Here is a link to the Dexter guide to measuring an axle. http://l.b5z.net/i/u/6149609/f/Axle_Measurement.pdf
A leading arm is just a trailing arm turned around BUT the brakes
have to be switched to opposite sides because brakes are "left" and "right" and they end up on the wrong side when axle is turned around. I think Dexter will build it with brakes to be a leading arm if informed. I think it is called a "Reverse Orientation" in that diagram of brackets. Notice how the long side of the bracket that comes down to the axle is on the outside
of the frame, not the inside, looking from the wheel of your camper you see a solid plate, not the axle sticking through a plate on the other side of the frame.
Look at the picture of the torsion axle, note how the bracket is longer toward the arm, yours is the opposite so... measure your bracket, length, height, width, AND how much of that length is on the front and rear side of the axle.
Scamp has that side cut short so it can weld to the metal frame where the floor drops. So measure your axle bracket.
Diagram your bracket, and axle measurements call either Dexter or Al-Ko and arrange to fax your diagram down for a quote. It will be a dialog, you give them some information, they ask some questions, you clarify. Eventually you work out all the details. You don't have to know everything up front.
I just ordered an axle from Al-Ko but I'm paying a local shop that builds and repairs trailers to handle that dialog with manufacturer and do the install. They are experts and the install is only about $200 You might want to go that route. They measure makes sure your axle fits and is installed by experts.
Al-Ko would NOT make a leading arm with brakes at a low articulation (angle) I ordered 22.5 degree down and that angle they will put brakes on. A leading arm 0 degree they would not, don't know about the 10 degree down angle that is between those two.
Worse case you will need to cut one end of the axle bracket short and square to match up with where your floor drops and the original is welded to that drop frame. You just don't want the end of the bracket you cut off to be the "long" side, you want that long side to remain so you can weld it to the main frame.
Scamp may not have made it with brakes but brakes can be added after the fact, they are part of the hub not the axle itself. They just assumed (maybe correctly maybe not) that it was not one of theirs originally.
