I’ve got a mint condition 2016 Silverado 2500 CC 4x4 and the 6.0 with 4:10’s that just turned 60k miles. I get asked often if I’d sell it. The answer is always no. Or at least no one has offered enough yet! Think I’ll hang on to her a while as posts like this are all to common on different forums.

As far as the 7.3 Ford gassers. We run a number of them in our ambulance fleet. 11 ambulances with a distributed call volume of 23,000 plus a year. Also have 4 F250 Battalion Chief trucks with them. One truck is at Ford now for engine replacement due to a lifter issue at 12k some odd miles, 2 ambulance have had engine replacements (one lifter, the other I believe valve issue going down into the engine) and numerous other issues like plug wires, coolant leaks, and oil consumption. Now admittedly, the ambulances get run hard. But all were low mileage issues, like well under 50k miles. I know the engine really hasn’t been out that long. But so far, they have been nothing like the pre 2020’s that had the 6.8. At least for us. Those engines took a beating and kept on rolling! YMMV.

Interesting to hear about your department's experience with the 7.3 gas. We don't have any yet, have 5 ambulances with the Ford V10. Just like your department, the guys beat them like rented mules and we have no problems that I've heard of. Most departments in our area are going with the diesel Ram 4500 for ambulance chassis, despite the extra length and cost.

Our logistics and acquisition folks have explored this option as well. However, our shop guys have basically wrote off diesel engines and fight them tooth and nail in our EMS units due to all the idling time and emissions issues. We have ordered solely gas since roughly 2016 in ALL Med units. And yes, the 6.8 was solid as a rock. I feel like the 7.3 may get there, it just isn’t there yet.
