On the mega cab 1/2 ton trucks Dodge used the 8 lug AAM 11.5” axle off the 3/4 ton with 8 lug wheels. I would think it’s likely they would use the AAM 11.5” axle on the TRX.
The 1/2 ton Mega was a 3/4 ton truck that they swapped out the rear leaf springs on. Everything else about that truck was 3/4 ton.
