Can Anyone Tell Me What Year....
What year wood frames in RV construction were replaced with steel/aluminum framing? I'm sure different companies might still use wood framing or a combination of various materials, but I am wondering ...

Most modern mass production RVs, particularly those you ride in, do not have framing above the floor. They are assembled from panels laminated around foam cores, using wood and plastic sheet materials, and aluminum, steel and wood stiffening members. Some manufacturers characterize the stiffening members as frames, but they are not, in the sense you are trying to envision.
Laminated wall construction was introduced to motorhomes by Winnebago in the late 1960s, and gradually adopted by most other manufacturers by the 1990s. Dates vary quite a bit, company to company.
Some lower production, higher end motorhomes still use framing rather than laminated wall construction. LazyDaze and BornFree, in C's, use steel and wood to frame the house structure. Newmar frames in aluminum, built on top of a wood floor. Holiday Rambler built motorhomes, including C's, with aluminum framing on a steel-framed floor, for Monaco, H-R and Safari brands, until Monaco Corp moved production of those models to it's R-Vision plant and switched to the laminated wall technology used by R-Vision.
You will find towables still stick-built, with wood framing, as well as unframed boxes using laminated wall panels. There are a few smaller TTs (and at least one brand of C motorhomes) using molded plastic shells, like a boat, rather than framed construction or a box assembled from panels.
