The firms that built their own frames all use certified welders. Honestly there were way too many failures in Lippert frames, and almost none from the other makers.
Simply untrue. There are failures with other manufactures as well including highly regarded companies such as Northwood (Saw first hand horrible welds). However, Lippert frames are on 1000's more RV's than any other frame on the road so of course you are going to see more issues. All of my RV's over the past 30 years have had Lippert frames. Zero issues.
