by "burning out" what is actually happening to them?
have you replaced the solenoid "S" terminal common as hell to see them loose causing a poor connection, have you bench tested the replacement starters? to see if they are actually defective
I'm thinking the connector on the starter is loose the fuse box (TIPM) will NOT kill a starter remember how simple these are 2 wires a hot battery wire and a signal wire for the solenoid, IF these all bench test defective you are getting crappy quality parts, reman starters are always bad luck in my experience, about the only thing to fail on the starter is the solenoid, what I see commonly is the solenoid wire (yellow or brown) gets loose causing a poor connection, that solenoid draws about 20 amps and must have a good connection.
have YOU PERSONALLY bench tested the starter with a jumper wire DIRECTLY on the starter?
I have also seen a few battery terminals cause a poor connection and not allow enough amps to spin the starter , our starters pull around 100 amps when spinning the engine.
with repeated starter failures I would also do a voltage drop test on the battery and chassis grounds.
honestly starter failures on THIS chassis is NOT common
