If a class 8 truck was designed to go off the pavement then they would make them more rigid and AWD.
Ever see a logging truck? No AWD just chained up wheels and locked diffs,pulling god knows how much wieght with mud up to the frame .If the tires find 'bottom' they move.
Plain jane kenworth or petes just like you see on I75Bird Freak wrote:

Never thought of that angle. You've got me convinced.transamz9 wrote:

I always find it amusing when this video comes up. You can tell the Ram is pulled far enough forward where only the right rear is unloaded. The Ford is teetering on the right front and left rear.

The Ram does not come down because there is too much weight on the left front (it is not balancing on the two tires like the Ford)
So what you are saying is that if they would pull the Ford forward far enough that the left front would be on the ground more that the frame wouldn't flex? :S Both trucks had the weight of the RR off the ground. The Ram is holding it's weight the Ford is not. Simple as that.
No not necessarily but it make it apples to apples. If you are not concerned with that I don't have a problem. You state both trucks have the right rear off the ground which is true, but only one truck is fully loading the frame.mich800 wrote:

If a class 8 truck was designed to go off the pavement then they would make them more rigid and AWD.- Curious analogy...but then do you think our light duty trucks should require
Class 8 level of drivers license (CDL requirement), 22.5" wheels, Drivers Log Book,
that they get fined if over weight, etc?
That would be refreshing to the over all safety out there, as personally think
way too many pickups/SUVs towing heavy are lacking...Bird Freak wrote:

- What is interesting about the test is now much more stress is placed on the frame with DRW which is not obvious though the wheels are further out from the frame and generate a leveraged loading of the frame.
For makes 3 different frames with this category for the F-350 pickup, F-450 pickup, and the F-450 chassis cab truck. No reason for Ford to go to this expense if it was not important and these differences coincide with increased payload and towing capacity.
GM made its 2500/3500 frames stronger starting in 2011 and Ram did the same in 2013 (first with only the 3500 and now with the 2500 truck frame as well) and they both did this when increasing the tow load capacity and rating for their trucks.
It does also affect handling and no surprise that more Ford truck owners find themselves investing in aftermarket upgrades like the Big Wig anti-sway bars.
