  1. Filed Mar 2, 2018Failure Feb 22, 20182,500 milesDunnellon, FLBody, Suspension, Unknown or other

    PURCHASED JANUARY 25, 2018. WHEN DRIVING FROM LAZYDAYS DEALER IN TAMPA, FL, I HAD TO HOLD THE WHEEL TO THE LEFT TO KEEP THE VEHICLE IN THE LANE. AT THE FIRST REST AREA I PULLED OFF AND SWITCH DRIVERS WITH MY SON JOHN. WHILE FOLLOWING BEHIND I NOTICED IT WAS LEANING TO THE LEFT REAR. AFTER PARKING IT AT OUR STORAGE LOCATION. JOHN REMARKED THAT IT DROVE LIKE AN OLD BOX TRUCK THAT WAS NOT LOADED CORRECTLY. I ATTEMPTED TO CALL THE DEALER DID NOT HAVE CALLS RETURNED. FEBRUARY 19, 2018 DROVE 321 MILES TO FLIMINGO NATIONAL PARK. HAD TO KEEP WHEEL TO LEFT TO GO STRAIGHT WHEN A TRUCK WOULD PASS US THE MOTOR HOME WOULD GO INTO THE RUMBLE STRIPS ON THE RIGHT HAND SIDE. ON THE RETURN TRIP WE STOPPED AT LAZYDAYS TO HAVE IT CHECK OUT. THE SERVICE MANAGER SAID THE NEXT OPEN APPOINTMENT WAS IN THE FIRST WEEK IN APRIL. THEY SUGGESTED THAT I LET IT THERE AND THEY WOULD TAKE TO INTERNATIONAL TO HAVE THE ALIGNMENT CHECKED. WITHOUT ANY OTHER WAY HOME I ELECTED TO DRIVE IT HOME AND THEN TAKE IT TO INTERNATIONAL OF OCALA. AFTER I ARRIVED HOME I LOOKED OVER THE COACH DESIGN AND FOUND THAT IT HAD BEEN BUILT WITH CONSIDERABLY MORE WEIGHT ON THE LEFT THAN THE RIGHT. BOTH SLIDE OUTS, GENERATOR, FRESH WATER TANK, GRAY WATER AND BLACK WATER TANKS FAVOR THE LEFT SIDE. WHEN I CRAWLED UNDER THE COACH I WAS COMPLETELY HORRIFIED. THE FRAME HAD BEN ALTERED FROM THE FACTORY BY A THIRD PARTY. THE WHEELBASE WAS ALTERED BY CUTTING A SECTION OUT OF THE FRAME AHEAD OF THE REAR DRIVE AXLE AND THEN WELDING IT BACK TOGETHER DID NOT FOLLOW THE NAVISTAR INTERNATIONAL BODY BUILDERS HANDBOOK. THE WELDS ARE THE WORST LOOKING WELDS I HAVE EVER SEEN AND CRACKS ARE ALREADY FORMING.
