Just like many, many others, the coupler on  adapter hose failed and doesn't allow gas to reach the burner in an amount required to even keep the grill lit.  This caused a problem on my last RV trip since I had planned to do the cooking, as usual,  for our family and another RV family.  I do really like the Q 2200 grill, but this hose has caused much disappointment for many users.  Is there any good solution?
