I would crawl under the TT and see if they use heavy duty spring hangers and shackles or like most in that class, thin ones.
Depending on how beat up the dirt road is or how long you're going down it will determine how well the Apex will do.
I would do smoother roads like gravel or dirt roads that aren't full of holes.
As a comparison my TT came with 16" tires, MorRyde's 3000 equalizer, thick shackles and spring hangers, shocks and grease-able bushings.
The Apex and my ORV are at different ends of the spectrum but in the real world the Apex should do fine in less rugged conditions.
There's a blogger that owns an Evo and travels all over in the boonies. So yes it can be done.
