Owner report 11419347 · 2021-06-02 (June 2, 2021)

The kitchen side slide out hydraulic cylinder burst/ruptured while under pressure due to the incorrect length bolt being used in the slide out rotating cross shaft. The bolt wore a hole in the cylinder over a 3 year period, and the cylinder shot hydraulic fluid all over the under belly of the trailer. Hydraulic fluid sprayed several 120-volt and 12-volt electrical connections and wires, and also leaked out of the side of the chloroplast. The fluid would have leaked onto the wheels and brakes if it had been in motion when the cylinder failed. Al…

This is a 43 foot fifth wheel RV. The frame near the front of the RV is showing signs of "frame-flex," or frame cracking. The attached pictures illustrate where the walls are shifting and creating wear marks; this is consistent with other RV owners experiences the same problem. This issue could contribute in further frame cracking that may result in significant property damage or even death. I plan to report this issue today to the manufacturer, Grand Design.

Owner report 11498848 · 2022-12-26 (December 26, 2022)

Our RV completly filled with the smell of propane when manually switching propane tanks while the furnance was running. The smell was coming from furnance vents. We checked the stove and the flame on the burner was unusually several inches higher in height. There no smell of propane in the exterior compartments or vents and isolated to the inside of the RV. All windows were opened and the furnance turned off to vent the RV to remove the gas smell. We believe this to be a propane regulator malfunction.
