Time for an upgrade from F350 to F550

Gentlemen,
PART I: Here we go. Our business has grown so much that we are considering replacing our 1989 F350 diesel dump that is in good shape with a F550 dump. We need to take into consideration that the vehicle will also be used for plowing residential driveways. The truck we saw this afternoon is a 2002 F550 XL, 4x4, 7.3PSD, auto, a/c, mason dump with 75,000 miles. It also comes with a plow. Tires are at about 60%. Asking price is $28,000. We mainly use the dump for mulch and soil, however we are expanding at a nicely controlled rate and foresee more use for a vehicle of this rating. I also thought of the Chevy 4500 but thought it would be too big to fit into residential driveways. Your thoughts and comments are appreciated. By the way, what may we expect in fuel consumption. I am assuming that the gears are 4:11s.
PART II: My son and I looked at another F550 and also test drove it at a Ford dealer. This one was basically the same set up as the other one, but was in better shape, had 28,000 miles on it, rode smoother and had better pick up. The interior seat was ripped at the driver's left seam. Has a plow frame but no plow. We can transfer our 9ft Fisher from the other truck to this one. We have a verbal agreement at $25,000 and the dealer fixes the seat. I am waiting to hear back on Monday if it is a go. This was also posted on Lawnsite to get both summer and winter view points.

I would go with the lower milage/price truck. Just keep in mind that the 30k service on the truck is coming up. The diesel will go for a huge amount of miles(7.3 PSD), so the engine's not an issue.

F550

sgoalie23,
You were talking about fuel consumption and assumed that the 550 had 4.11 rears...I am not 100% sure, but am fairly positive that 4.88s were the only ratio available for 550 diesels. Will definitely burn a little more gas than your 89, but the newer engine with fewer miles than the 89 may help make up for that a little bit. As far as size goes, I don't believe that the difference is that great from your 350 dump, but again, not 100% sure...just trying to give my 2 cents. What year is the 550 that you have the verbal agreement, just out of curiousity. I would also go with the lower mileage truck. Good luck with whichever you choose. Let us know the result.

L/S Diff.

sgoalie23,
I have never heard that you could tell that an axle was a limited slip by its look. Not saying it isn't true, just I have never heard that. I always thought the only way to tell, other than taking it apart, was by checking the code on the axle tag. I believe the clutch packs that make it limited slip are all internal and do not affect the outer shape of the diff. Has anyone else heard of this?? If so, please enlighten me. I've never met a salesman I could trust! That's pretty low mileage for an 01...just a little over 5k a year...can't go wrong with that. J.

They use the same rear axle housing for open or limited slip diffs. Tytpical salesman instead of reading the codes and looking them up in the computer he just BS's his way through it.
 
#8 ·
1st if youre only hauling mulch / soil and plowing, just go with the 350....no need to be flashy, and you could save alittle$$$...+ WATCH out for the oil pan and the oil cooler system, i JUST bought a 2000 ford f 350 PSD and had to replace both with in 2 months how much ohhhhhh juuuuust $2,600, so make sure you get on youre back and check that out, if it is rusty DONT buy it!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
 
#9 ·
plus i would'nt buy anything with a meyer on it, only fisher for me!
 
#10 ·
If the deal goes through, we have a 9Ft fisher on another truck and we will switch to the 550. The picture is of the first truck we looked at. The second has the frame only for a Curtis but no plow. We should find out later today about the deal.

That is the biggest post I've ever seen. I felt like I was falling as I was scrolling down to the end. I almost needed a parachute. :waving:

yaaa, i dont know about that, i dont think god pays to much anttention to computers and cut and pasteting????

Sgoalie23--Before you buy----A guy on the site has a 99 f450-- for sale--going out of bussiness--had 7.3--nice truck can't remember if it had a plow on it! Had it listed around 23K--I think he would entertain a serious offer! He was from Abington Ma. Name was Emerscape! Some Jokers here were offering him 15K! JMO that is way too big for a driveway rig! Unless there 100' long and uphill both ways! If you could find a nice lot for it to work in thats what a 550 needs! Both trucks your looking at seem like nice rides! The guy's post is just a little way down--"Whats a fair price"

Like I said before go with the low mileage truck.
The higher one may have not ever had any services done to it also.
You can always add plow mounts but you can't erase miles on it.
Look at the drivers door sticker to see what it came from the factory with.

F550

sgoalie23,
Congrats on the new rig. Hope you can get it plowing if we ever get more snow around these parts. Be sure to post some pics when you get a chance. J.

The salesman also said that it had a limited slip diff. He stated that you could tell due to the shape of the differential.
which end was he talking out of. sales men will tell you any lie to make a sale.
fords stock limited slip is not very impressive. i can barely tell my truck has one.
