you summed it all up perfectly. Kinda makes me wonder About getting out of the truck game, just sell the RV and do something else. For me a truck is handy and a nice for pulling my trailer for camping but some people have to have a truck for work or whatever.
I’m with the ecorattle group and now the dang frozen doors and whatever else is on the list. Would have jumped ship to Tundra already, at this rate I could overlook the terrible fuel mileage, would be good if tundra had better payload.

I'll NEVER own another freaking LS engine (or GM, for that matter) ever again. I MUCH rather own the 5.0, or the 3.5 EB I have now (passed on the V8 for having more issues than the 3.5EB). On the ratcheting noise, which only happens when cold, AND basically if you're looking for it (at least the way I drive), I have ZERO concern. As a mechanical engineer, it's not a noise that sounds detrimental to the engine at all. It's obviously not a refined noise, but not a detrimental one either IMO. Leave THAT to the awful piston-slap all of my 3 LS engines had. As far as the Tundra not having direct injection, I'd count that as a PLUS, actually. I also regret not looking at them, based on the negative reviews on this forum. I don't need anything close to the towing limit of my truck, and even its lousy payload (mine is 1,458 lbs) is more than enough for my needs too. I bet the Tundra is more than enough. To be quite honest, towing with an F-150 at its highest rated capacity is not smart IMO, and wouldn't do it anyway. If you're going to tow near 5 digit weight, you need a 250 chassis IMO. After dumping the factory oil with the new M1 0/30, the engine is silent even on cold (50ºF) starts, and I've only heard the ratcheting ONCE (and faintly) when I forgot to shift to 2nd (Going downhill out of my driveway so using engine braking in manual mode) quickly, and revved the engine to 3K rpm. So it's basically a non-issue for me. Not happy with the dismal fuel economy, but again, the V8 was having more issues, and no max tow with it, so reluctantly went with the EB, but not regretting the decision after reading all of these posts. But just wish it was a trouble-free V8

I may have it slightly but I noticed that after had the battery disconnected for roughly 45 min last weekend, it was quiet on all fronts. I get a little warm startup rattle now that I have a little time that has gone by but thought that was interesting. Mine is a 2017 but still a 2nd gen ecoboost

I noticed that, as the adaptation goes degenerating the shifting, it seems that that the torque converter doesn't open totally even when you are idling.
I have the shifter in the column and I can know exactly when to disconnect the battery (each ~500 to 800 miles) by the effort needed to put the truck in drive...
Even vibration in idle is different....
I can feel the engine vibration when the transmission is bad and after the battery disconnect I can't feel any vibration when idling ....

Did you notice if it is easier to put it in drive from park?

In addition to the rattle upon deceleration, just started noticing that my 2018 5.0 has a cold rattle during acceleration from a full stop. It’s happening when I use very light throttle and goes away once warmed up. I have approximately 14k miles. This is a new noise. Anyone else having this happen? I’ve also had the frozen lock syndrome last week. Rear door would not lock. So was stranded for about 20mins till the door finally locked shut. Once I got home I was unable to open the door, but this issue resolved itself. To top it off, I too have the warped dash on driver and passenger sides. It’s worse on the passenger side. I tried getting Ford to do a by-back, but was declined. I have a lawyer working toward that goal. Still waiting to hear something.

Haven't really heard the off acceleration until this afternoon. It's definitely there! My shop had been pretty good about the stuff I've brought to their attention. I'm sure I'll get the same response as everyone else but it's a shot.

I have an engine ping while accelerating from a stop. Try premium gas and 90% goes away. I have an appointment next week to discuss why I have to pay for premium when 87 octane is recommended. So far I have the off throttle rattle, engine ping, and the typewriter tic.
