You could definitely
give me a truck without a V8, but I'm just going to to trade it in or sell it.
I've seen some videos about the GMC vs RAM. The 5.3 cannot keep up, but the Chevy/GMC 6.2 beats any of the other current N/A truck engines. I don't recall what bed they had, but regardless, I don't see the 5.3 making much headway.
If you take a look at Ford forums, you'll also see that not everyone gets the fantastic MPGs I see mentioned in this thread a few times. Many are getting the same as us.
As others said, did not buy this truck to be a race car, I agree. It would be nice to be able to keep up, though.
I hear it all the time from my Ford-fanboy brother-in-law on the EcoBoosts, Ford's put thousands of hours of testing into it, its so much better than the V8s... blah blah.
He said that about his 2008 F-150 with the 5.4 as well, and he traded that in for his current 2016 EB F-150 because it was having major engine issues.
EDIT: I looked at Fords before buying my 2020 Ram. If they would have a Rambox equivalent, I would have looked at the upcoming 2021 models, and if I had ended up in one, it would have had the 5.0 V8 (assuming they don't have another V8 in the pipeline for non-Raptors).
