My dad is looking into buying a new work truck. We own a landscape company and will put a large dump bed on the truck while also pulling a bumper pull landscape trailer. Sometimes pulling around 10k. We both drive 2500 Lmms and love our duramax's, but we have a 2001 F650, and it does great. We are currently looking for another large truck, we would prefer the duramax, but have heard that the 4500 and 5500 squat more when pulling that say a F450 or f550 would. I would like your opinions or how your truck are doing. The negative to the F650 is that we will not buy a 6.0 or 6.4, so we would have to buy a 7.3 which is an 03' or older. I'm not a Ford hater right now we own 6, from 90' to 03'. But I do love my Duramax, and the Allison

Squat???

The rear squat down when u put a bumper pool trailer. I know that airbags can easily fix this. Mostly I wanna know how well ur trucks tow, especially if you use the hell out of them everyday. Not abuse just work hard

It would depend on which rear axle truck has. Axles can be from 13,500 to 19,500 lbs.

keep in mind that some of us carry five car trailers and 40ft plus trailers with either air ride system or both springs and bags. There are also different length chassys for example look at Gasuout's truck and mine

Ok, ya I know our F650 is a four door, with I believe 12ft bed, maybe 14. And on the axles, are those specified by chasis length, or u just have to find one with the heavier axles? I just want to prove to my dad that the duramax is the way to go, not buying an old 7.3 F650.
I love the 4500 and one day I will have one. Not a C series but topkick or Kodiak.

A Topkick or Kodiak is a C series.

I just meant not the work series.

We have the 5500 with 12' dump boxes on them and they do not squat at all. We have put 4 ton of asphalt in it and it is spilling all over the sides and it is sitting lower, but by no means bottomed out. It does drive real light in the front, but landscape material would not even phase it. We have a few F650's and they are a heavier duty truck than the Kodiak, but not by much. They also stay together much better than the Fords. In my opinion the Kodiak's are the best all around work trucks out there. We just bought two more this week because they are going fast, we have over 30 Kodiak/topkick's in our construction fleet from dumps, flat beds, mechanic trucks and I have a personal Monroe Kodiak that is just a toy puller and a toy. I hope they start making them again in a new updated body style when the economy levels off.

Alright Fozzy, that's what I like to hear.
Thanks for all the input

I scale in on the truck itself at at 23-26,000. Im 16,000 empty they do good with weight. Up around 26,000 the front end gets a bit squirelly. There great Id buy 2006 and up if I were you, 2007 is the best year IMO.
