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 if the industry has shifted to mostly aluminum or steel frame design and if so, what year roughly they might have started doing that?

To put this in context as to why I need to know. I am wondering which RV's and what years are less succeptable to wood rot/leaks because their frames are "mostly" aluminum/steel or combination of non-wood products.

Or am I totally misinformed and most RV's are still made with wood frames?

The majority of RVs today still have wood frames....Alum. frames started in the 50s & 60s.................................Maintenance is the key to the lasting of any RV......... Getting away from sectional Alum. roofs was probably one of the best improvements...
