Ford V10 Triton

What Lumpty said is spot on. I have an 03 V10 and it has the full length spark plugs. Anything before that has the shorty plugs.

I had a 1999 V10 in 03 and drove to Alaska and back 11,500 miles pulling a Honda Accord. Several trips to Iowa and Florida without any problems from the V10. I think they are a solid unit and would not be afraid to own an older one even now.

I might also say that I used Amsoil full synthetic and never changed oil on my Alaska trip until I returned. Then I changed every 10,000 after that. I was very happy with that old V10.

Good luck on your choice and Happy Travels

The V10 got the 2v “PI” heads in ‘03, which raised HP to 310 in the A chassis and 305 in E-Series cutaways. Those heads also increased the spark plug hole thread count. BTW, consensus is 28 ft-lbs dry cold torque is a set and forget amount of twist when replacing the plugs.

In the ‘05 model year is when the 5R110 was introduced. Given the incomplete chassis inventories, the safe year for those would be ‘06.

The 3v heads I believe ended up in the Class A chassis starting in ‘09. Again, the safe year looking for that would be 2010. The early years of those heads had some issues with plugs breaking on removal. More recently, the 6R140 trans was added (guessing 2017-18?).

My Chieftain was on the original v 10 and had no problem with spark plugs blowing out, etc. the problem I had was the motor sucking in ground water due to air pickup location and got a "snorkle" from Ford for that. talked to a fella at a campground who had a newer model and was sort of gloating about that until we compared gas mileage and his smirk disappeared.

Same here... I had a first year ( 1999) V-10 and it gave us great service in our 36' Pace Arrow Vision. Well over 130,000 miles when I sold it without any issues other than the serpentine belt idler pully bearing and the starter relay failed... but both of those were in the first couple of years and covered by warranty. I did change the air intake as Bumpy mentioned. I wish my other vehicles had such reliable engines !

So I would look for an 08 and up. Easiest way to tell is if the dash has (D) 3,2,1.

FYI...I have a 2006 National with a 2005 F53 chassis, and my tranny is the 5 speed.

Yes, I wasn’t sure on the year, but figured it was safe saying that year. Especially considering MH’s are built on a year old chassis sometimes.

AL, it depends on what time of the year you MH was made. It could have been that Ford up-dated the drive train early.

Agreed. I just wanted to point out Ford started transitioning the transmission a bit earlier. My MH was built in mid-2006 and delivered September, 2006.

The spark plug issue was more due to Ford's limited torque specs and not due to the limited number of threads. It has been proven that if you torque the plugs to 25 ft. lbs. they will not come loose.
