It takes a LOT more room to get that one ton truck turned around than a 3/4 ton truck.
That Furd F450 turns sharper than any other one ton truck out there (pick up truck, I know the HD Volvo's turn sharper) But I just cant afford the price.
In the newer Fords there is no difference in turning radius between a (same length) F250 and F350 SRW. Even on the F350 Dually there is a "wide track" front axle (basically the F450's) that allows for a sharper wheel cut for a reduced turning radius.
Technically the F450 is not a 1ton.

Here is some info from an accepted expert on thedieselstop:

Depends on the year.
Since you asked the question in the '99-up forum, I'll assume you mean '99-up.
For all '99-up PSDs, there is no difference in the front spring rate between identically-optioned F-350 SRWs and F-250. But pickups with different options can have different front spring rates. So an F-250 could have higher-capacity front springs than an F-350 SRW with different options. Go by the front spring code.
For the '99 models, the rear springs and the rear axle were different. Stock tires were different, but the F-350 SRW tires were available as options for the F-250.
Beginning some time in the Y2K model year and continuing through the '04 model year, Ford began installing the same rear axle and rear springs on most F-250s as were standard on the F-350 SRW. Stock tires were still different, but again the F-350 SRW tires were optional on F-250s. So for many pickups, the only difference in identically-optioned F-250s and F-350 SRWs was the spacer block in the rear suspension of 4x4s. F-250 4x4s had 2" spacer blocks, and F-350 SRW 4x4s had 4" spacer blocks. (There are no spacer blocks in 4x2s.)
For '00 thru '04 models, check the spring code on F-250s. If the rear spring code is "B", then you have the same rear springs as F-350 SRWs. But if the rear spring code is "A", then you have the lighter F-250 rear springs.
But beginning in 2005 model year, there is a definite difference in the F-250 and the F-350 SRW. The rear axle is different. The rear springs are different. Stock wheels and tires are 17" on the F-250 and 18" on the F-350 SRW. But still you could order F-350 SRW tires and wheels on F-250s, and many did.
Quote: Tires and wheels, yes. Rear springs and rear axle, no. F-250 4x4 longbed PSD 4x4 has 10,000 pounds GVWR. F-350 SRW longbed PSD 4x4 has 11,500 GVWR. The difference is in the rear springs and rear axle weight capacities. Everything else, including frame, brakes, front springs, shocks, engine and tranny are the same.
Here is the axle specs:

The only exception that I know of is that GM doesn't make a shortbed 3500 SRW.
I have a 07 Chevy dually Duramax full four door and eight foot bed and four wheel drive. I live in an area where we have lake effect snow and have not had any trouble in the snow with four wheel drive. I drive it all the time and the biggest problem is the length. Sometimes I will have to back up four times to park, but usually that isn't case. It also corners nicely with the extra wheels on the back and that is with or without a load. The only thing I will do when the tires wear out is to put bigger ones on.
Sounds to me like in that axle comparison they're comparing the 11000-lb 37-spline Dana 80 in the DRW F350 (and some F450's) to the 35-spline 9750-lb Sterling/Visteon 10.50" in the F250/F350SRW trucks. Visteon listed the axle specs as the same for F250/F350SRW last time I checked.
