2008 FOUR WINDS HURRICANE Suspension Problems

WE BOUGHT A 2008 FOUR WINDS HURRICANE 30Q WITH A FORD CHASSIS ON 10/31/07 APRIL 10, 2008 WE HIT A RUT AND THE RV BEGAN VIBRATING. TIM THOUGHT WE HAD BLOWN A TIRE. STOPPED, GOT OUT, NO BLOWN TIRE. BACK IN, STARTED DRIVING, WAS OK. THOUGHT IT WAS A FLUKE. IT HAPPENED AGAIN ON THE WAY HOME AND WE FIGURED WE'D HAVE IT REPAIRED ALONG WITH ALL THE OTHER WARRANTY WORK WE HAD DONE. ON THE WAY TO CAMPING WORLD IT HAPPENED AGAIN. THAT WAS 3 TIMES TOO MANY. CAMP. WORLD. TOLD US IT WAS A WEIGHT PROBLEM. WE MOVED THINGS AROUND AND IT STILL HAPPENED. DOESN'T HAPPEN ON EVERY BUMP, BUT IT HAPPENS OFTEN ENOUGH TO CAUSE ANXIETY. WE'VE TRAVELED ALL OVER THE SOUTH HAD THIS HAPPEN TOO OFTEN. THE A/C HAS GONE OUT 3 TIMES, WE'VE HAD LEAKS IN THE REAR AXLE TWICE, WE THINK THEY ARE CAUSED...
