I saw this 1948 American LaFrance 700 ex firetruck on Facebook Market Place.
It has no drive train and no bed, just a roller for $1500 OBO.
The dreamer that I am and my imagination is the only hobby I can truly afford, I immediately thought of this as a basis of a toy hauler.
Use a school bus drive train, like a Cumming or Cat 3126 with an Allison automatic and some sort of ramp body...
