Just a guess but it could be your brake switch.

Did you change the tail bulbs. 9/10 this is the problem with these trucks if all other lights work. They burn out/short very easily and are poorly sealed in the assembly and yes both can go out at once. I've had it happen on 2 late model 1500's. 7443 LL from WM $6.

LED? or standard bulbs. Assuming Standard, change the bulbs. Believe they are a 7440, not the 7443 from above which should be the front turn signal bulbs. If they are LED you have more diagnostic work to do. First step, make sure there is power, quite common for there to be a break in the wires from gravel damage or a bad bend in the wiring.

Brake lights work, as do the signals, only the running lamps don't.

Brake but not tail/running lights. Gotta be fuse/wire short? Not think it be canbus.
