there's nothing wrong with plastic, provided two conditions are met:

1. as tegger says, it needs to be loosely mounted.
2. there needs to be normal pressure in the system, not excess due to a
leaking head gasket.

regarding 2, a lot of times, radiators are replaced because of
"overheating". a low level head gasket leak can persist for a long
time, with the chemical and pressure stress that places on the system.
if a radiator cracks under those conditions because a prompt and
effective diagnosis of the root cause was not made, i don't think
there's a huge amount to complain about.

fyi, plastic/aluminum are a great combo for internal corrosion
resistance and seal persistence - that's why they're used. just make
sure you don't buy the cheapest one and you should be ok.

The radiator in my Jeep is rigidly mounted to the front grille, but the
hoses are about two feet long each.

Radiators expand and contract with temp changes.

Everything in the car expands and contracts with temp changes. You can
either install two foot long radiator hoses, or put up with a floppy
radiator. ;^)

The reason for "floppy" radiator installation is to minimize the effects
of torsional stress. All frames/bodies flex which ain't good for any
high pressure vessel...

The part you miss is that the radiator itself expands and contracts,and the
plastic tanks may not stay sealed to the aluminum core,nor is ordinary road
shock and vibration healthy for the plastic/metal seals.
