I don't know but I intend to hang on to my 6.8L V10 Ford until they pry it from my cold, dead hands.

A lot has been said how these new smaller engines do such a great job and even a half ton PU can pull larger trailers. I'm not a mechanic. I do basic repairs and can get by. I have learned a lot about these smaller engines because I sell hay here in Wyoming. I talk to my customers, expecially when they come driving up with these smaller new engines that claim they are better than the old big cu. in. engines. Just isn't true. Everyone I have talked to say they are sorry they bought the smaller gas engine. It is all advertisement. Those small engines just will not tow horse trailers with 3 or 4 horses over the mountain roads we have here in Wyoming. Unless of course you want to travel at tractor speeds over the mountains.
I'm hoping that when my V10 wears out I'll be able to get a rebuilt V10 to replace it. If I get a larger TT or even pulling my present stock trailer loaded with cows I need a diesel. However, I hear there are problems with the urea system in very cold climates. The urea freezes and thaws. Although the tank is supposed to expand and contract apparently it causes cracks and the urea leaks out and you are stranded. If you are stranded in Wyoming in the winter you are in trouble. Especially if there is no cell phone coverage in the area. Just IMHO. I'm no mechanic, I just talk to people that are buying these new vehicles. They just don't like them.

Anyone remember the Chrysler turbine? The fourth-generation turbine engine ran at up to 44,500 revolutions per minute and could operate using diesel fuel, unleaded gasoline, kerosene, JP-4 jet fuel, and even vegetable oil. Air/fuel adjustments were required to switch from one fuel type to another and the only evidence of which fuel was used was the odor of the exhaust.
The engine had just 1/5th of the moving parts of a traditional piston-based internal combustion engine (60 rather than 300). The turbine spun on a simple sleeve bearings for vibration-free running. Its simplicity offered the potential for long life, and because no combustion contaminants enter engine oil, no oil changes were considered necessary. The 1963 Turbine's engine generated 130 brake horsepower (97 kW) and an instant 425 pound-feet (576 N·m) of torque at stall speed, making it good for 0-60 mph in 12 seconds at an ambient temperature of 85 °F (29 °C)—it would sprint quicker if the air was cooler and denser. More than 1.1 million test miles were accumulated by the 50 cars given to the public, and operational downtime stood at only 4%. Think it is time to revisit this design!
The downside ? It sounded like a vacuum cleaner.........

Jay Leno has a motorcycle powered by a turbine (from a helicopter)
He had the real life experience of melting the bumper of a car who got too close behind him at a stop light, but ya it is a rush in motion.
Turbos and direct injection on the other hand have proven their worth in trucks, and now the reliability problems are worked out they are ready for medium duty use and Ford has done well by getting into that and GM is playing catchup for good reasons. A turbo gives you a variable displacement and other than on a really heavy load you just don't need 7 and 8 liters and with gas in the U.S. headed towards $5 as earlier as this summer (and it is already over that where I live) this is the future. I hear the Econoline replacement will use the 3.5 turbo. If 3.5 liters is not enough then stroking it or reducing the static compression can easily increase the torque till the stress limits of the block are reached.

Most buses, cube vans, delivery trucks, etc all use front engines but for some reason, the vast majority of RVs with front engine are gas. Obviously this isn't a replacement for DPs but I'd much rather than a front diesel and a front gasser.
As far as diesel's, Ford's got the 7.3 Power Stroke (up to 275HP/515 ft.lbs torque) and GM's got the 6.6 Duramax (up to 400HP/795 ft.lbs torque).
Money.
You better believe it, this whole country revolves around getting it one way or the other if they got to steal it.
Long as theres a big CEO for a gas company sitting on their duff collecting moneys & much as the gas companys are in control of this country, the auto makers & gas companys in each others back pocket working hand & hand, there will be engines that will use lots of gas or diesel fuel.
Now high as diesel fuel is today, I can see them going diesel engine.
MFGs want you to buy something every year, so you think they care how long an engine last.
Normally when a company replaces things, it is because it is costing them to much money to keep producing it, so the 6.8 V10 shouldnt go away, because how much has Ford had to spend replacing the screwed up engineered heads they designed for them, that you cant get a Ford dealership to replace the spark plugs in.

No, I didn't say that. The urea apparently is heated by your radiator when your car or truck is running. The problem is the urea temp is warm when the vehicle is running. When you park the vehicle in 20 or 30 below zero weather it freezes. The thawing and freezing of the tank causes problems although there is supposed to be some flexing in the tank to prevent damage. I think if the tank just froze and thawed once a day you may not have a problem. If you use your vehicle and start and stop it several times a day the freezing and thawing really seems to be hard on the tank.

I heard they were going to use twin Ego boost's. One in front, one in back. Just running one to do CAFE testing.

I see on workhorse's web site that they are using the maxforce 7 diesel engine in their front engine chassis. Anyone have this in a motorhome yet? How quiet is it? I know there were some FRED chassis with the cummins 6.7 in it. How are these front engine diesels working out. Are they fairly quiet? I know the diesels in pickups now are very quiet compared to my 1998 dodge with the 5.9 cummins. My truck is really loud and clattery if that is a word.
Thanks

I've often thought especially with all the Eco push the gas MH is on its last legs not because it's not viable but because the govt ( who knows whats good for us all ) doesn't want you using it. My bet is diesel in the smaller units and diesel electric in the larger .. And BIG bucks for both making rving a thing we will talk about in the future as the glory days !
My post's are my opinion The advice, comments etc are free and worth what you paid
