Now I'm a little worried about the hitch in there... surely they wouldn't have put a hitch there if it would bend, Would they? I'll look underneath and suggest hubby put them on someplace more stable underneath. Not sure what rails are, but going to look and see if the frame underneath would fit the wooden pieces he made.
