2006 MONACO COACH CAYMAN Structurebody Problems

THE FRAME AROUND THE ONE PIECE WINDSHIELD HAS COME LOOSE ALLOWING THE WINDSHIELD TO COME LOSE TO THE POINT IT IS ABOUT TO POP OUT. IF THE WINDSHIELD HAD POPPED OUT AT 60 MPH, THERE PROBABLY WOULD HAVE BEEN A MAJOR ACCIDENT. I TALKED TO THE SERVICE REP FROM ALLIANCE (NEW OWNER OF MONACO). HE WAS FAMILIAR WITH THIS PROBLEM WITH MONACO. HE SAID IT WOULD TAKE 18 HOURS MINIMUM TO TAKE THE WINDSHIELD OUT, FIX THE FRAME, AND PUT THE WINDSHIELD BACK IN. COST: BETWEEN $2000.00 AND $300-.00 WE ARE CONCERNED BECAUSE AFTER ALL THIS MONEY WE HAVE SPENT (REFER TO FIRST FORM SUBMITTED), THERE ARE STILL PARTS OF THE ENGINE THAT ARE RUSTING. THE MECHANIC WE HAVE BEEN USING SAYS THAT HE HAS NOT SEEN THIS MUCH RUST ON UNITS 20 - 25 YEARS OLD. WE GET ONE THING FIXED AND SOMETHING ELSE BREAKS. WE HAVE NOT USED...
