One aspect that never seems to get mentioned on 5th wheel towing with 1/2 ton pickup threads is that 1/2 ton pickups normally have semi-floating rear axles whereas 3/4 ton and up trucks have full-floating rear axles.
Rather than try to explain the critical differences between the two, I'll link to the following WEBPAGE that explains and illustrates both axle designs.
A key difference not mentioned is that breaking a semi-floating axle shaft outboard of the bearing can result in the axle hub and wheel becoming detached from the vehicle, whereas breaking a full-floating axle shaft results only in a loss of drive to that particular wheel which is retained by the hub and bearing arrangement.

While I agree on 1/2 tons not being built as strong, when's the last time you read about a newer 1/2 ton axle breaking? JMO but most 1/2 ton RV'ers are weekend warriors. I highly doubt they put 10,000 miles a year towing as full timers.
I gave up on the Full Floating/Semi Floating a while back. I just live with the fact that my with my 2500 i have TWO BIG bearings on each side to support the load rather than one smaller bearing.
That said there are 5ers that can be safely towed within axle capacity with 150/1500's. I have also stated before I would much rather see 150/1500 pulling/carrying a 5er slightly over GVWR, and Rear GAWR as long as they had enough wheel and tire capacity than a long 10,000# TT, the 5er will be way more stable.
BYW; Nice link.
