Scheduled appointment with dealer for the Grand Design Frame Flex recall today, 22 May 2026. Approximately 4 hours after dropping the trailer off the dealer called and said that the technician found significant frame flex and that the unit was unsafe to be towed. No other information was provided. I did ask for the measurements that the TSB 24-001 requires to be filled out ans submitted to Grand Design. The lady that called was completely unaware of what I was asking for.
