I have a Fuzion 302, 2008, and had the same problem.
Where the "receptacle" bolts onto the table top....
Loosen all the screws. On the side that slopes down, remove the screw and add 2 or 3 washers as a spacer/shim. At the 2 screws next to that one, add 1 or 2 washers. You may need slightly longer screws.
That worked for us.
I suppose you could also shim the receptacle on the floor in a similar manner. We didn't have to.
Our table was also too high, so we bought slightly shorter legs.
Now we have a folding, rectangular table with adjustable height....from Camping World....to user as an alternative. I don't like it, my wife does.
Cheers,
