Having a weird issue with my truck where there is a strong smell of propane outside and sometimes inside. I’ve read posts about people having a strong weed smell coming from the truck, this isn’t weed, definitely more propane/natural gas. I first noticed it towing a 6k ish camper down to the smokies. I was running up some decent hills at 70mph and there was a really strong smell of propane. I thought I was passing some gas mines or something but it stuck with us for the rest of the trip down but was faint. I did think maybe it was my camper leaking propane but ruled that out after smelling it again after driving on the blue ridge parkway without the trailer. We would get out at scenic lookouts and the truck stunk of propane outside. Had 3k mikes on when it started, now at 7k and still smell it sometimes. It’s usually during or after towing. I have the the eTorque 5.7 motor with 3.92’s. Wondering if anyone else has had this issue.
