WE REPRESENT THE OWNERS OF THE TRILOGY 5TH WHEEL RV. AT MANUFACTURE, THE CABIN OF 5TH WHEEL WAS PLACED ON BENT FRAME. THIS RENDERS THE VEHICLE INCAPABLE OF LEVELING THROUGHOUT. THE VEHICLE WAS INSPECTED BY OUR EXPERT, REVEALING 23 MM TO 40 MM DIFFERENCE RIGHT TO LEFT, DEPENDING ON WHERE THE MEASUREMENTS TAKEN. WHEN ONE ATTEMPTS TO ATTACH TO THE RECEIVER IN THE TRUCK BED, UNABLE TO MOUNT FLUSH (DAYLIGHT CAN BE SEEN). CONCERN EXISTS REGARDING THE UNEVEN WEIGHT DISTRIBUTION DUE TO THE CONSTANT UNEVEN/UNLEVEL NATURE OF VEHICLE, RENDERING IT UNSAFE SHOULD THE VEHICLE NEED TO COME TO A SUDDEN STOP AT HIGH INTERSTATE SPEEDS OR WHEN ENCOUNTERING CROSS WINDS. IN ADDITION TO SAFETY CONCERNS, THE INABILITY TO LEVEL THE VEHICLE HAS CAUSED PROBLEMS WITH THE SLIDES, SUCH THAT THE CONTROLLING MOTOR HAS BURNT OUT, THE BEDROOM SLIDE LEAKS AND THE MAIN CABIN SLIDE WILL NOT FULLY EXTEND, MAKING THE VEHICLE UNINHABITABLE. OUR EXPERT FINDS THAT THIS VEHICLE IS INCAPABLE OF REPAIR. MANUFACTURERS HAVE BEEN CONTACTED WITHOUT RESOLUTION AS OF THIS DATE.
