Confusion comes because older (much older) Scamp 13's had a leading arm axle (arms pointing toward the front on the trailer) with a downward angle on the axle arms. If one of those was angled upward, it would indeed be shot.
As Eddie says, what you're seeing is correct for a newer Scamp with a trailing arm axle.
Rubber torsion axles are good for 15-20 years, and can be usable well beyond that. On a 2010, I would only give it a cursory check for damage, very unlikely.
On an older trailer there are a few things you can check to verify axle condition. (1) Check clearance in the wheel well. There should be at least a fist clearance between the top of the tire and the
fiberglass when the trailer is resting on the wheels. (2) Check for axle arm movement. Raise the trailer by jacking on the frame just behind the axle. The wheel should drop down several inches as the trailer rises. Little or no movement means the rubber inside is hardened and the axle is shot. (3) Check for unusual tire wear, which could mean the axle is worn out or bent.
This one doesn't have
brakes, but like all recent Scamp 13's it has the mounting flange, so
brakes can be added.
