| Okay, so I'm having my friend weld me a towe hitch for my Z and was looking for some structual help on what would be the strongest method to use. Method A illustrates a slit cut into the 2"x2" tube and the L bracket inserted and welded on all edges. The top/bottom triangles would also be welded if necessary for additional rigidity. Method B illustrates the 2"x2" tube just placed on the inside of the L bracket and welded on all edges and possibly the same tirangle supports welded on the top and bottom. The example below taken from zhome looks like he's used method A but any imput is appreciated.

 So which is the best method???? 
THANK IN ADVANCE!
