Had four new fivers in the past 10 years or so, never replaced any circuit cards yet. But everyone of them had foam and sawdust from the ceiling come down after being towed, their entire time we owned them.

The circuit board on my 2018 Sundance failed a few months after I took delivery. The nearest Suburban authorized service center couldn't even look at it for two months. So instead, I bought a board on Amazon and replaced it myself. The interesting part was when doing research, I found that Suburban had recently re-designed their circuit board. Also upon inspecting my old board, I could see where the circuitry was burned. Then I found a picture on line of that same circuit board with burned components in the exact same place. So it was either built with faulty components or a bad design to begin with. I opened a claim with Suburban and with that evidence got them to (relucantly) reimburse me for the cost of the new board as they only wanted to honor their warranty if the work was done by a authorized dealer.

I made sure I purchased a board of the old design. No problems since.
