    Good evening everyone,

    I used to be on here quite a bit but unfortunately, when my wife got pregnant and had to quit her job in the midst of us qualifying for our house, I had to get rid of my 2014 DC.

    Now we are back in the market again and I’m looking at getting a second gen to keep the cost low. Budget is around 14-17k. Looking at a double cab again. My question is in regards to the 5.7/4.7 debate. In my search I’ve seen many beautifully maintained 4.7l 2007-08s that have under 120,000 miles for the 14k range. Yet, the 5.7s seem to be around the 17k range for 150,000+ miles.

    What would you guys pick? My 2014 was a 4.6 and I thought it was fine, although I do like a lot of power. But I don’t tow, and don’t haul much other than the dogs and stuff for projects around the house. My main concern is reliability and cost of maintenance. I’ll probably keep this truck for about 3 years or so.

    How many miles a year would you drive it? You’d probably get the extra money for the 5.7 back when you sell but nothing wrong with the 4.7 given that you don’t tow or haul. Only other thing I’ll mention is you’ll pay around $1,000 to do a timing belt on a 4.7 if it hasn’t been done while the 5.7 has a chain.

    They are both great engines. There was a million mile 2gen Tundra with the 4.7. Which is also used in many high mileage Land Cruisers, etc. And of course there are many high mileage 5.7 also, I think there are some in the 400-500k range on this forum. I say go test drive one with the 4.7 to see if it has enough power for you. Or Go with the one that has the best maintenance records. I personally prefer the 5.7 but you can't go wrong with either one.

    The beauty of your dilemma is that both choices are winning decisions.
    If you are on a monetary budget and you know deep down you do not need the bigger engine, then do not get it. Who cares if you go a little slower? Your wife will like slower anyways now as will baby. The dogs won’t notice any power loss and call you out on it and you don’t tow anything daily. MPGs will be a little better and maybe insurance is a little less(just a guess, no clue if that’s true or not). The lower mileage is always a good thing as well and three to four years from now you have no clue what could be going on anyways. I would go 4.7. Mamma and Baby and budget win. Happy wife Happy life.

    My 07 5.7 Tundra has right at 400k and I’ve never a major engine repair. It’s been a construction truck pulling trailers exc and she still going strong. It’s the best Ive every owned. I’ll let you know in another 13-14 years if my 2019 limited is just as good

    Have you already driven both? I had the same dilemma and after trying the 5.7 it’s a no brainer. Smiles per gallon not mpg! I’m also not sure the mpg is even much better with the 4,7 especially if you often drive on hilly terrain since the 5.7 won’t work as hard but I could be wrong.

    Thank you everyone for the responses. Man I have missed this forum and this community. This is a huge part of what makes Tundras so great.

    I have not driven a 4.7 yet, but I imagine it isn’t that much different than the 4.6 I owned right?

    I have a 9 mile commute to work. I drive no more than 15,000 a year with occasional trips out of town, camping, etc.

    I know the main “issue” with the 4.7s is that it has a timing belt. Other than that, are there other large maintenance costs?

    I used to care only about power and “status” of a big ole new truck.. I bought a 2017 F150 Ecoboost from new, then an ‘18 Nissan Titan, before buying the 14’ DC Tundra 4.6, and then acash purchase of my 05 F150 5.4 with 183,000 (With all the misfires and issues that thing had I’m sure a 4.7 or my old 4.6 would feel like a hot rod in comparison..lol)

    Now that I’ve gotten away from the land of $400+ car payments I’ve learned how dumb I was with money in spending every dime I earned. Now all I really care about is reliability and cost of ownership more than anything and will just be thankful for a solid truck again. The most I’ll be doing to this new truck is some all terrain tires and possibly a level once suspension parts are worn.

    One consideration: I'm not sure the fuel economy will be very different between the two engines. That being said, I would always go with the lowest mileage vehicle with the best maintenance records I could afford.

    After owning a 4.7L since last February, I think I would have been better off with a 5.7L. I live in a hilly area and it can be a slug sometimes. On level ground power is adequate but passing power is not a strong point. I have to think really ahead about WOT passing. Maybe a 2WD would be fine with a 4.7L.
    No wonder a 4.0L is only available in a 2wd RC.

    MPG is not that different. I go with a timing chain, so 4.6 or 5.7 for me. Our 05 Sequoia with a 4.7 does have to work quite a bit harder than the 5.7 in my Tundra on steep grades or when towing. Easy choice for me, 5.7 > 4.7 in every way.

    5.7L for sure
    I wouldn't even think 150k is broken in yet

    My 5.7L gen 2.5 gets better MPG than my 4.6L Gen 2 ever did.
    The 5.7 has better power as well.

    That said, the 4.6 did haul the truck camper and tow the boat with no issues other than less power and economy.
