I too question when will we reach the peak of this bubble, though as long as the overall economy continues to grow, I don't think we are anywhere close, though the rate of growth may slow. I attribute this to a few factors, first build quality or the lack of it likely means the service life of RV's they are churning out will be shorter, as many of us know rot from water intrusion tends to be the number one killer of all types of RV's. Second the US population is growing, look at those historical sales figures, then compare them to US population growth. Looking at RVIA's historical numbers https://www.rvia.org/historical-rv-data the first year they produced more than 300,000 units was 1999 with 321,000 units (the same number that were produced in 2013), however the estimates suggest the US Population has grown by nearly 50 million people since 1999 (278 vs 325 million today, which is over 15% growth), so population adjusted those 1999 production levels would equal to 375,000 today, this of course fails to account for shorter service life of todays units. It should also be noted that in 1999 the 2007 period was fairly stable, except for the dot com bubble bust, which only caused a 6 & 14% downturn 2 years in a row, vs the 9,32,30% drops when the bottom fell out in late 2007, where production went from 390,000 in 2006 to 165,000 in 2009.
