Its nearly an identical truck, chassis wise, and they share 99.9% of the same components. when they designed the molds for the 21 TRX cast parts, they didnt know the RHO would be a thing in 2025. Doesnt make sense to spend millions to completely remake millions of dollars of molds to change 3 letters when the part functions identically. These molds are outsourced to mold making machine shops, take months to make, and cost a pretty penny. To be honest, I'm amazed they didn't just name this truck the TRX again to avoid the harnesses, hard goods and so on having "TRX" on them..
