Forward Diesel Repair

Forward Diesel charged me $674 to travel 16.3 miles & remove a starter from my RV.
They charged me $674 for 45 minutes worth of work.
They spent 5 minutes troubleshooting, confirmed the problem & pulled the starter. That's it. That's ALL they did. No parts, no towing, nothing. $674.
