What size tires can you run? Personally, I’d be very tempted to go the cheap route of buying a new fork for it. Get one with lower rack mounts and carry your heavier panniers on low rider racks in front and run some Arkel Dry Lights with your lighter, bulkier gear on a light rear rack. It should tour just fine as long as you can run at least 32mm tires. You could probably get away with 28mm, but personally I’d definitely choose the 32-35mm range if you can fit them. If it doesn’t have a triple crank on it now, you should Definitely look into that.
