I’d guess my net environmental impact is just now lower than US average because, despite my fuel consumption when moving my home, it’s tiny, energy independent, and it doesn’t move far or frequently. I don’t really know. I just don’t want to be judged unfairly, particularly when seeking help trying to do it even better.
I want to downsize my truck for cost and fuel efficiency. I’ve had this truck, my first, for a year, 3.5k miles. I’ve towed the trailer a short thousand miles without incident and including city, highway, and interstate.
Current setup:
'19 Chevy 2500 6.0L 4WD
Hitch towing ~2.5 tons GVWR (14’, enclosed, tandem, brakes)
Getting 8mpg @ 70-75mph
Next truck budget is $10-20k. I’ll keep it probably until the frame rots. I’m planning on replacing shocks & wearable steering components, am not averse to some work.
Should I target a 1/2 ton gas (leaning Ford 5.0L 4WD), a different 3/4 ton gas (which and why), or a 3/4 ton diesel (leaning Dodge Cummins)?
The paper numbers say I should get a 1/2 ton gas. But, my more experienced friend thinks I’ll be a lot happier spending more for a diesel because diesel engines can last a long time, it’ll at least double my fuel efficiency, and it’s a little extra overkill for an easier tow.
I’m open to all informed perspectives. What’s my best plan and why?
Edit: I kept the Chevy 2500 6.0L because the local market didn’t support transition on the sale side. I also bought a '98 Dodge Cummins 12v diesel that needs work. It’ll eventually replace the other truck.
Kinda dead, but there’s a community for vehicle suggestions.
Toyota. You’re a fool to buy domestic, especially if you’re only towing 2.5 tons.
OK. Then, I ask with humility and respect, “Why?”.
My objection to the Tundra is that I could buy a diesel for nearly the same money that’d give me double the fuel economy and double the miles. And, it’s not going to be much more reliable than a domestic tuned and maintained by myself.
If I had to have the best gas 1/2 ton on the market then I think it’s a Tundra. But, I’m not looking for the best tool. It seems a 1/2 ton is a mistake. I want best value under the assumption labor is free.
What am I missing?
Diesel is clearly better if you are driving 20,000+miles per year. However you are not doing near that, so it won’t be worth the extra cost. Today diesel is so much more expensive than gas that the real advantage is only that diesel engines last longer, and in your case the body will fail first.
How much of your driving is towing vs unloaded? If you are only towing then a large engine is better - displacement = torque = more fuel efficient. However if you are mostly unloaded something like the Ford Ecoboost engine is much more fuel efficient unloaded and when towing you lean on the turbo to use more fuel (as much as the large displacement engine!) and so still have the power - but the engine won’t last as long overall and will break more often - thus not a good choice if you mostly tow.
I would lean to the 3/4 ton trucks. While a 1/2 ton truck has the specs to do the job, all of them are aimed at the luxury car market these days, and so they will make compromises that make them not as good for real work. 3/4 ton still is targeted at people doing real work and so they will have better compromises. (if you were asking 30 years ago a 1/2 ton would be fine)
Do you need something now? Electric trucks are just coming out and should start hitting the used market soon. They only do about 100 miles when towing, but are much more environmentally friendly if you can live with that limitation. I wouldn’t think about sticking with the truck you have now for 3 more years to see what happens here (and also 3 more years to get real world experience with how electric trucks really work for people in your application)
How hilly is your terrain, and how often do you pull the trailer?
Mostly flat and not pulling often = 1/2 ton, although you might occasionally be annoyed with getting going slowly with the trailer.
If hilly and/or pulling often going for the 3/4 for more consistency would be better.
It is like picking between economical hatchback. Being low powered isn’t generally a big deal if you aren’t loading the back with heavy stuff and driving around flat roads, but if you use the hatch to move a few hundred lbs a few times a week uphill then getting one with a more powerful engine makes sense even if the hatch size is the same.
The biggest advantage to diesel in my outdated experience was low speed torque for heavy loads, especially trailers.
It could be the northern Rockies. It could be Iowa (flat). Most of the miles will be interstate and highway. I’ll be pulling the 2.5t trailer almost exclusively for 10-12k miles. Then, I’ll have many short haul loads in the 1-4t range for maybe 2k miles. Then, it’ll spend maybe a third of its remaining life with that same 2.5t, the other two thirds with less than 0.5t payload.
Based on what we’ve both said, it seems like you’d favor a 3/4.
I’m not worried so much about pull power acceleration as efficiency at 70-80mph.
Oh, and you will wear out a truck where you regularly pull the max load a lot faster than one where you regularly pull closer to half the load. Those max loads are not intended to be regular.
Wasn’t sure if your first year was representstive of future years.
My first year was about 1500lb payload. I went easy on it. But, there’s no such thing when pulling at the limits of the transmission & drive line. This is why I thought of a 1/2 ton, 2.5t sitting at around half the max capacity. But, because I’ll be towing full time for awhile, the accepted perspective seems to be to overkill even a bit more.
I have a 2WD 2019 F150 with the 5.0 I use to tow my horses around. With the tow package, I think its max is 12900lbs and it does a hell of a job on stuff in the 6-9k range but get up in the max range and it struggles a bit. I would say it gets about 8-12mpg depending on what we tow with it. I think it’s rated for 19/21mpg just on its own. I get about 17/19mpg just driving it around.
It lives a light-duty life hauling horses down highways and South Texas caliche roads, but I am happy with my f150 most days. I think when it comes time to replace it I will go back to the f250 for the higher towing capability but stay gas only because everything we run is gas.
Hopefully, my experience helps, have fun truck hunting.
