Quite frankly this very small cracked appeared over in Wyoming on I80 when the road construction was terrible and the transition was about a 6 inch drop with no warning ..
My hairline crack is 1/8 to 1/4 max and hasn’t changed in 8 years..I marked the edge of the crack and stop drilled with small drill nut.. 3/32 I think..it was what I used while on the road back in 2014 when this occurred..
Many owners would not ever notice this tiny crack in the filon on my fifth wheel
With the many thousands of miles towed since this tiny crack appeared and some rough roads we travel on yearly I’m confident if there were any structural issues the crack would have increased.
Then again I don’t have X-ray vision.. I try to apply sound judgement and decisions based on my aircraft structural background and 50 plus years of mechanical background when I make choices and decisions.
Had the crack continued to grow Id have pursued further.. but with 8 years of towing and zero change in crack..it’s sealed with clear proflex so I can see it and the edge mark I made years ago
The larger cracks many are posting would cause me great concern and would be repaired immediately or I would have gotten rid of that RV…
