Own a 2021 Rebel (factory order) with ecod. Approaching 8mos and 10K mi of trouble free, amazing MPG performance. On the drive home from the dealer, 1250mi, averaged 28.7mpg. One, and only, gas stop at 850 mi on odometer (33 gal tank). Averages 25+ MPG mostly rural driviing. Jury is still out on 3rd gen ecod reliability. 1st and 2nd gens did have their share of problems. Part of the equation is driving scenario. Those doing a lot of city, stop and go, idling might be better served with gas engine. Longer distance, less stop and go, hauling, might be better served by a diesel.

Does look like a bear to work on. Engine is fairly recessed in engine bay on the 1500s, difficult access. Oil change on 3rd gen ecod 1500 is PIA as oil drain is just above crossmember, so installed a Fumoto valve to route oil away from the crossmember. Electronics in these new trucks is formidable and I'm a retired EE, but I do love the HUD and adaptive cruise.
