2014 CROSSROADS REDWOOD Wheels Problems

WHILE DRIVING ON US 89 IN CALIFORNIA, MY FRONT PASSENGER SIDE TRAILER TIRE EXPLODED. HWY 89 SECTION HAD NO TURNOUTS OR SHOULDERS FOR ME TO STOP. THE TIRE IS A MARATHON ST235/80R16 LOAD RANGE E WITH APPROXIMATELY 10,000 MILES ON IT. I AM FANATIC ABOUT VEHICLE MAINTENANCE AND TIRE SAFETY AND THE TIRES HAD THE RECOMMENDED AIR PRESSURE. I CONTACTED CROSSROADS AND WAS TOLD THAT THERE WAS NOTHING THEY COULD DO FOR ME. I SPENT $102,888.00 ON THIS FIFTH WHEEL AND I HOPE THAT I CAN AT LEAST GET A RESPONSE FROM THE MANUFACTURER. CROSSROADS KNEW OF THIS TIRE PROBLEM BECAUSE IN 2015, THEY CHANGED THE TIRES FOR ALL THE NEW MODELS TO LOAD RANGE G OR AN OPTIONAL LOAD RANGE H. MY TRAILER IS A 36RL AND IT HAS A GVW OF 16,000 POUNDS. WE BOUGHT THIS TRAILER IN FEBRUARY 2014. WE HAVE USED IT THREE TIMES AND NOW...
