Well we had a 6.5' TruckCraft Allum. Dump Insert Installed today. (Dropped it off at 8 and my phone was ringing for pickup at Noon.) Picked it up at the dealer then raised it half way..they let it back down. Made a few stops about an hour later my worker calls and says the Check Engine light is on... Anyone know what it could be???? Either way im going to take it in tomorrow morning and have them fix it..
