I am contemplating how to move forward with my recalled Tundra. I have enjoyed the truck but am thinking about cutting my losses and moving to a larger truck. I tow a travel trailer occasionally but also could use the additional capacity to potentially move equipment & materials for my construction company. I really could use a larger bed as well since I keep a dog box in the bed most of the time.

I have seen a few on here talk about the complexity of "modern diesels"... so what does that mean? DEF and diesel, what else do I need to know?

I am leaning towards an AT4 or AT4X, seems better bang for the buck compared to a Tremor. I would like to maintain some semblance of ride quality, maybe best bet is going with AT4 and putting on some Fox or Kings? I understand with the payload capacity the ride is not going to compare to my Tundra.

Yes the modern diesels obviously have the emissions issues. But also complex turbos, high pressure fuel systems and they are larger heavier engines.

It's worth test driving the gas 6.6 from Chevy and the 7.3 gas from ford. If you come from the half ton world you will find the Chevy more comfortable. I have 150k miles on mine no issues. Very easy to daily and none of the VVT issues from the Chevy half tons. Lighter and smaller engine than the diesel means longer suspension and brake life and easier/cheaper maintenance.

Modern diesels like to run. Hot shot haulers routinely put 4-500k miles on their modern diesels but they run them all the time and maintain them.

If you're not driving a lot I would go with gasoline. Diesel gets much better gas mileage but given the $11k upgrade for diesel and the price difference you will need to drive a couple hundred thousand miles before it breaks even.

And don't check that as I made up that math.

I'm at about 20-25k/year with a lot of highways to job sites.

That should be fine. I'm about 35k miles/year with a 60 mile round trip to work. I have 135k miles on my 6.7 with "knocks on wood" no issues.

Pretty sure its a fuel filter change with the oil change. And of course a big cardboard box and plastic jug of DEF fluid... quite the paradox right?

Use the green pump! (Not yellow)

Kidding…are folks dumping the recalled Tundras? I heard dealerships aren't taking them.

My last few trucks have been a '15 Duramax, '18 Powerstroke, and '20 Powerstroke.

Just change the oil and change the fuel filter every other oil change. Be selective about where you get fuel. I typically just topped off DEF when I changed the oil.

I never had an issue, emissions related or otherwise, with any of those trucks. Hardly towed or worked them at all, pretty much just drove to work and back.

I don't really have any advice for you other than to share my current predicament.

My 2023 Silverado 1 ton diesel has been at the dealership since 6/24 undriveable and the part has been on back order the past 2 weeks after being diagnosed.

The valve body in the transmission failed but luckily it's under warranty. This is the same transmission found behind the 6.6 gas Chevy engine with a 10 speed and a twin to the ford 10 speed transmission behind the 6.7 & 7.3.

I would do my best to find a nice used gas 6.6 gmc 3/4 ton with the 6 speed transmission. A 2023 or older.

I regret getting rid of my 2016 Duramax with 200k trouble free miles

I would seriously look at the 3.0 GM diesel in the half ton. I jumped from that to the 6.6 duramax 3/4 ton. Sometimes I think I made a mistake, even thought I tow a 34' travel trailer fairly regularly.

my biggest need is with the 6.5' bed but 1/2 ton long beds looks so out of proportion.

I just went the other direction. Had a 2019 F250, 6.7 turbo diesel, awesome machine. Short bed was plenty for me. She was beautiful. She rode really rough unloaded. Like knock your fillings out rough.

Just wasn't using it to haul at all. We have a small poling skiff that a 1/2 ton can handle no problem. That's it. Our horse and cattle trailers are handled by a 3/4 ton ranch truck.

Was essentially just using it as a daily driver. They are big and tough to maneuver if you have to drive and park in Houston Dallas Austin etc. Mine was stock and wouldn't fit in many parking garages. They are targeted heavily by thieves, so get a good anti-theft system if you go w an f250.

Maintenance is quite a bit higher than gasoline trucks. 2 batteries when they go out. Oil change takes more oil and more filters, def 2-4 times a year depending on how hard you drive and tow. Tires are more expensive. And the diesel exhaust emissions systems can cause problems. As in, my truck threw an exhaust filter error code in Arkansas in January and stranded me in limp mode for 4 days. Now I was duck hunting so not the end of the world, but the ford house had it for 4 days and charged me 500 bucks to do diagnostics and clear error codes and never found anything wrong with it.

So, for me, not everybody else on this board, for me, it was a hard bit logical choice. If you don't mind spending the extra money on maintenance and purchase costs and you can deal w the maneuverability, go for it. There is nothing, nothing, like putting your pedal down and hearing that big diesel and turbos wind up. It would pull a house off a foundation. I hauled a TT and 44 HP tractor on a big utility trailer and it never knew they were back there.

If all you want is the long bed, get a gas 3/4 ton. The modern diesels are a maintenance nightmare unless you are doing what others have mentioned and piling on miles doing diesel stuff. I am a long time diesel owner with 3 Powerstrokes over a 15-20 year period (7.3, 6.0, 6.7) and they all progressively got to be more and more of a nuisance. I put 237k on my last 6.7 which is nothing to sneeze at, but it came at a high cost of ownership. When I traded it in a year ago I decided I didn't need that big truck and motor anymore and haven't looked back.

Gas 3/4 ton all the way. Detroit's last attempt at a decent truck.

That's s rare one. There's so many more with a diesel. I think GM must build them in batches because I saw a bunch a couple months ago. My local dealer had a couple for a few days. I love the exterior but wish the interior wasn't black. Now they have a SLT with tan interior and I really want to grab it but wasn't planning on buying for at least one more year.

I'm loving my Ram 2500 Cummins. Tows better and better towing MPG than my Powerstroke. Zero issues 20,000 miles in. Plus I haven't had death wobble (knock on wood) like I had with my Ford.

Well done.

Everything else aside, there is no comparison to the feel of mashing the pedal in that diesel over a gas engine.

Until it goes into limp mode because the valve body in the transmission failed.

I haven't truck shopped in 8 years. Are the new diesels across all brands really 90-100k?

Did you ever deflate your tires when it was empty? I'm doing that with my 2015,, but the stupid tire sensors grouch at me.

I inflate to max when towing, but drop to 50 or less empty

Depends on the trim. For GM, the lower trims start in the mid 60s and go up from there. An SLT is about 80k. Denali or High country can easily get to 90 or more.

I had a client with a Denali diesel 1 ton dually that was $120k+.

Obviously depends how crazy you get with packages and options. Big discounts only really available on Rams right now.

You will love that truck…. Right up until it gets stolen.

Congrats!

Ya I'm definitely nervous about that. I hid an air tag in it and very careful about how I use the fob. I reached out to IGLA but they apparently are out of business or have terrible customer service.

Girl at work, her husband had a high-end Denali 3/4 ton stolen out of his company parking lot. Cameras showed it took them all of 3 minutes. Probably in Mexico somewhere. This is in DFW.

I think they scan for the air tags pretty easily. You almost have to get a lock for the steering wheel these days.

If they have an I phone they will know an AirTag is following them. You can easily remove the speaker in the air tag to help delay the perp from finding it.

I have an airtag in my ATV at our ranch and it would take hours if not forever for someone to locate it.

This is what I did as well. Remove the speaker in the airtag and think of a place for it you can't get to quickly and it won't rattle around.

Research what it costs to replace the water pump, alternator, oil pan, injectors, starter, etc. How many timing chains or belts does it have and how often do they need replacement? Also look into whether it has a Bosch Cp4 pump and the issues that commonly go along with that.
