I never said the full floater was Magical, just that it is far stronger and safer! Break an axle on a semi floater and you are likely to loose a wheel, break an axle on a full floater and you may loose the ability to go, but you will still be on all four wheels.

There are well known axles under 1 tons, such as the Dana 60 HD, that are semi-floaters, with over 6000# GAWR's, FYI.

IF you could find a way to break an axle, particularly a Toyota one, you'd likely be in a situation so dire, or so slow, that the loss of a wheel is not the problem.

And on any decent modern truck, the rear caliper / brake assembly would hold the axle / wheel on. The Tundra included.

Dana 60 rear axle
From Wikipedia,
"The Dana 60 rear axle was first introduced in 1955 as a full floating axle in Ford F-250's and is still used today.

Manufactured in both full float and semi float variations. The semi float axles have GAWR up to 5,500 lbs and the full float axles were rated up to 6,500 lbs.

Full floating variants are common. Semi-floating and full floating axles exist, but are less common. Axle spline count varies, with 35 spline being the most common."

I think you are mistaken on two fronts, one the types of Dana 60 axles in use, and I doubt very much that the disk break caliper mount would hold the wheel in place with 2,000# to 2,500 they will easily break off the caliper mount.

Don't always trust wikipedia. The E350 has a semi-floater D60 HD that is rated for 6000# in that application (actually axle capacity is 6300). linky pg15 It used to use a D60 FF back in the early 2000's, not any more. Wikipedia is written by whoever gets inspired to type, and if it is not corrected, it can and is wrong.
And the caliper only needs to manage the side load, not the weight if the axle breaks. (again, when does this happen?)
