i was "building" a f350 on the ford site and came across a "heavy duty" suspension upgrade and a "plow prep" upgrade. anyone know the difference, and why you cant get both on the same truck? (can you plow with the heavy duty upgrade?)
This is per the 2009 F-350 Order Guide, but I suspect that they will carryover into the 2010 model year.

So, there are a couple of differences. But, to answer your latter question: Yes, you can tow with the Heavy Service Suspension Package.
The main difference is that the Heavy-Service Suspension option does a "one up" front spring upgrade, in other words one step up.
The plow-prep goes all the way, usually, to the heaviest front-springs available.
I had heard in the past that the plow prep was a +2 on the front springs and the heavy service was a +1 on the front springs. But you may be right Krewat. I didnt know this back in May when I ordered my 09 and I kinda goofed. Alot of folks here talk about lifting there 250's by putting 350 blocks in and swapping in the 'X' code springs or whatever. I figured for the minor price difference I might as well order it that way, a 350 with the heavier springs. But I did the wrong package (I ordered the heavy susp not the plow prep). Plus I use more truck more for hauling in the bed that towing so another advantage of the 350. Not a big deal though, I'm sure the heavy suspension package will help with payload and make it set a little higher at least, probably no where near level though. I might actually want to plow with it too, IDK. Right now I have a 42" blade on my old cub cadet... it does ok and probably doesnt make nearly as big of mess out of the gravel driveway than a truck would. But it does take a good hour for my small driveway and getting the cub to start in the cold is always a problem.
For my '01, I got "T" front springs, and the overloads and a big flat bottom leaf on the rear, and a steering stabilizer, with the heavy-service suspension.
But the newer ones, who knows what Ford does especially with the "computer selected" phrase in the documentation
