Limited data — recalls on file
NHTSA has just 0 complaints on file for the 1981 Oshkosh F Series — too few to judge reliability from owner reports alone — but one recall campaign applies to this year, so any used example should have its VIN checked for completed recall work.

1 NHTSA recall campaign on file. Recall repairs are free at franchised dealers.
Defect
THE AIR SYSTEM SERVICE RELAY SUPPLY LINE ON THE #2 AXLE IS INCORRECTLY INSTALLED INTO THE FRONT AIR SYSTEM RESERVOIR. CONSEQUENCE OF DEFECT: IF FRONT SERVICE BRAKES WERE TO FAIL, THE SECONDARY, OR EMERGENCY BRAKING SYSTEM FOR THE #2 AXLE, WOULD NOT WORK. THIS WOULD LEAD TO A COMPLETE LOSS OF BRAKING CAPABILITY WHICH MAY CAUSE AN ACCIDENT. CORRECTIVE ACTION. REINSTALL THE AIR HOSES INTO THE REAR AIR SYSTEM RESERVOIR.
The record is thin — 0 NHTSA complaints — so owner-report data can't strongly confirm reliability either way, though 1 recall should be verified as completed.
Yes — NHTSA lists 1 recall campaign affecting the 1981 Oshkosh F Series. Recall repairs are free at franchised dealers; check the VIN at nhtsa.gov/recalls to confirm the work was done.
