If it was mine that would have happened long before the claim count reached 70.
Lemon-laws for RVs are a tricky thing. We purchased in NC. The laws there are weak and I think are limited to RVs < 10,000 lb GVWR. Virginia's laws (our state of residence) are better, but it is a difficult process that appears to be stacked in the manufacturer's favor. And again, the manufacturer has to be given the opportunity to correct the problem. I can't recall if Virginia law provides for 2 or 3 attempts to successfully repair the issue. Additionally, the issue has to be one that prevents use (current issue does) or has a direct safety impact.
At this point, our attorney is on stand-by and is just awaiting our instructions following the dealer's assessment of the slide box and GD's response.
