2015 KEYSTONE FUZION Structurebody Problems

WE WERE IN THE GIFFORD PINCHOT NATIONAL FOREST TRAILING OUR UNIT. THIS WAS ON A NICELY PAVED ROAD, NF90 NORTH OF COUGAR, WA. HAD TO TURN AROUND SO WE COULD FIND A PLACE FOR THE NIGHT, AND DID SO AT A T INTERSECTION. I GOT OUT OF THE TRUCK TO INSURE SAFETY AND GUIDE MY FIANCE'. I NOTICED THAT THE WHEELS DID NOT LOOK RIGHT. I CALLED MY FIANCE' OUT OF THE TRUCK TO LOOK. HE AGREED, BUT SAID WE NEEDED TO GET THE TRAILER STRAIGHT WITH THE TRUCK BECAUSE WE HAD TWO INDEPENDENT AXELS. HE PULLED THE TRAILER BACK ONTO NF90 GOING SOUTH WHERE IT WAS IN LINE WITH THE TRUCK AND THE ROAD WAS LEVEL. IT APPEARS AS IF THE DAMAGE HAS BEEN ON-GOING, EVIDENT BY RUST. AT TIMES WE HAVE GONE 70MPH. AT THE TIME WE NOTICED WE WERE BARELY MOVING. WE ARE LUCKY TO BE ALIVE....
