I have never broken a solid axle, in a Jeep on Rubicon, or pickup out hunting. I broke a Ford F250 IFS working on my 5 acres though...
I thought the Twin I-Beam rode fine. But
Both of the ones I had sagged like crazy. And, I see that all the time looking at F250/350 with that front end, and the leaf springs. The leaf springs do not work as well/last when the axle pivots on an arc from the center attach point. It wears the springs too much. The system works much better on the F150 with coil springs.
When I switched my F250 long bed extended cab to a straight axle, it went from turning like the Queen Mary to turning on a dime. I was shocked by the huge difference in turning radius, shocked... And, very happy.
The IFS in the F250 was a hybridized Dana-44, the Dana 50. The Dana 60 straight front axle is a lot beefier. I had the IFS apart to replace broken axle shafts; it was definitely weaker than the beefy Dana-60.
The Sterling rear axle in the Ford is a good strong axle.
I was never excited by the GM IFS. Rode nice, but sat low and limited articulation.
Mine had the ZF 5-speed. Not a very strong tranny, and 1st gear was more car like as compared to a creeper first gear.
Which 5spd are you referring to? The NV4500 was a great tranny.

whew! i feel just opposite, first i understood we were talking about 3/4 ton pickups do you think gmc or dodge go any better? off road the twin i beam can carry more speed than a solid axle.i use a 3/4 ton truck to catch and doctor cattle,solid axles will break off.the later models twin i beam is heavier. as far as a stick it is the same brand as the gmc which are a step above a dodge [5th gear falls off].i had 5spd ford with about 300,000 on it when i sold it.i would get a auto anyway.i like the 351 ,it is strong enough to pull a 20,000 lb trailer full of hay to the barn or a 14000 lb cattle trailer to the sale barn.if going further get a diesel.empty the mileage is good for a 3/4 ton gas. for me, i like the twin i beam robertn has a point about a solid axle being cheaper to run.if you want a solid axle,get a single rear wheel 350.
