Something to ponder...

As I stated in my earlier posts, HP is a metric that measures the rate of energy consumption or delivery, and in the case of a vehicle, is kinetic energy delivery.

Every physical "thing" posseses some form of energy, but no physical "thing" is energy.

Energy is a metric that exists between all fields of engineering and it is the metric that allows the engineering fields to be bound together.

So while HP is interesting and necessary when taking a systems approach, it doesn't provide any real insight into speed without looking at it as a graphed dependent variable related to the independent variables of torque (force) and angular (linear) velocity.

BTW, I much prefer my diesel over a gas engne for the towing that I do...

I just finished a trip form southern Ontario to Jasper Alberta through the USA pulling our Freedom Express 242RBS 3 adults lots of toys and the dog with a 2012 F150 Super Crew FX4 Ecoboost and this little truck makes the diesel vs gas a very difficult decision.
We averaged about 10 mpg US and handeled head winds on the plains, mountain passes and everything we threw at it with ease. The truck gets a very consistant mid to high 20's mpg without the trailer.

The Ecoboost may be a strong point as it is a gas turbo, but diesel is still ahead in towing torque and mileage I tow almost twice what you are pulling and get 11.5 to 12 towing and 20 highway empty, and weigh 7,400# empty.

I'll agree that diesel is ahead in towing torque, for now. But the mileage is questionable compared to a gas turbo. This is fords first attempt with the 3.5 twin turbo. Remember how the first diesels ran? lol In fact, even the new diesels are still rattle buckets which your neighbors have grow to hate sunday mornings.

And what happens when more clean air regs catch up and diesel remains more expensive? $100 oil changes, fuel additive's, 3 fuel pumps, injectors.. When a pump or injector fail they can ruin the entire engine. No thanks.. I'll run a 8.1 or 6.8 gas for half the purchase price without ear plugs thank you. If the gas fuel pump fails it stops..

Well diesel is not needed for all towing, and they are not for everyone.
Just remember the gas went through the EPA issues about 20 years ago, good old run on etc. I don't think it will take diesel that long to get it right.
Gas users always complain about the standard maintenance, my old 460 used 7 qt. of oil every 3,000 miles, I now do 11 qt every 7,500 miles. I only have two fuel pumps, diesel in my area is currently 10 percent more than gas, and I get at least 50 percent better mileage towing than a 8.1 if not 100 percent towing the same load.

There are those that will always stick with what is "safe", but I had diesel before and did feel safe. The difference between gas and diesel pulling a load is night and day.
I will be one to say if you stay under about 8K for the trailer, a F150 EcoBoost will do great, but remember it is a Turbo gas engine, it will be interesting to see how well they hold up.
Part of the reason diesels last is they are burning a lubricant not a solvent!

You will see from time to time that posters that switch from a gas to diesel, and clearly see the towing difference.

I am strongly considering getting a Diesel 3500. One concern is that Diesels seem to be "dirty" clouds of black smoke etc.

Can anyone tell me what the NEW diesel engines are like if they have to meet lets say California emissions standards.

All the research that I've done points me to a diesel engine for my new truck. The only remaining concern is "how dirty" we have visions of black disgusting vehicles :-)

Thanks

New diesels do not smoke unless someone adds a tuner.....and even then, most tuners on lower power settings do not smoke much if at all. The newer diesels have particulate filters in the exhaust to prevent smoke.

I would not buy a used Dodge from 07 through 09. They did have some issues with the exhaust filters, that may have been fixed by software updates. I believe the 2010 and newer have most of those issues fixed. I bought a new 2012 and have no issues at this point.

I don't have much knowledge of Chevy and Ford diesels, but my guess is they similar issues during that time period.

Diesels are not for everyone. They can cost a suitcase full of money to repair when out of warranty. From my perspective, unless you just want one, or tow a lot, get a gasser. If you tow heavy or just want s diesel, buy a new one.......or get an older one from the late 90s or early 2000s. The exception to that in my opinion is the 5.9 Cummins. I believe they were good up through 2007 when they changed to the 6.7. If you buy an older one, make sure you have some money in savings for repairs...

I now see you want a one ton. The will most likely mean a diesel rather than a gas engine unless you buy an old one. Go drive all three and buy the one you like. They all have good and not so good features... My opinion is that you probably can't buy a bad new one from any of the manufacturers.

How's that for a ramble......?
