Limited data — recalls on file
NHTSA has just 0 complaints on file for the 1999 GMC G3500 — 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.

Defect
ONE CAMPER EQUIPPED WITH A TWO-DOOR REFRIGERATOR MANUFACTURED BY THE DOMETIC CORPORATION, MAY HAVE A DEFECT IN THE BOILER TUBE. PRESSURIZED COOLANT SOLUTION COULD BE RELEASED INTO AN AREA WHERE AN IGNITION SOURCE (GAS FLAME) IS PRESENT.
Consequence
RELEASE OF COOLANT UNDER CERTAIN CONDITIONS COULD IGNITE AND RESULT IN A FIRE.
Remedy
THIS CAMPER HAS BEEN REPAIRED.
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.
