Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 1977 B100.
The 1977 Dodge B100 emerges from historical reliability data as a notably quiet model year, generating only two total owner complaints and a single recall campaign, with structural integrity accounting for the primary reported concern. This minimal documentation positions the 1977 variant among the more reliable iterations within the B100 series timeline, suggesting a period of relatively solid manufacturing consistency compared to surrounding model years. For researchers, this sparse complaint record—anchored by the single recall and focused structure grievances—indicates reduced systemic risk, though the concentration in structural areas demands careful inspection of body condition when assessing specific vehicles.

Owner-reported issues, recalls, investigations and service bulletins on record with NHTSA — an unfiltered look at what owners actually experience.
Owner complaints about the 1977 Dodge B100 dominate in one area — the structure, 2 of 2 reports (100%), well ahead of the next concern. That matters, because the structure are also the target of recall 80V-027 on this vehicle — so the single most useful check before buying or servicing one is confirming it was actually performed. 0 of the reports describe a crash and 0 a fire — a small share of the total, but worth weighing against the structure pattern above. These are tallies of what owners actually reported to the federal government, not an editorial score — and higher-selling models naturally rack up more reports.
