I like what you did there! I ended up cutting tiny cross sections out of the rack flooring to fit the double jerry can mount. It bolts through to plates that clamp the mount to the bars. The only way for it to line up correctly was to cut the flooring... I'll see if I have any pics lying around.
May need to start ordering more panels as spares.
I decided not to cut out areas for those mounts. I think the flooring is more than strong enough. (Guess we will see). I do plan on adding some more secure mounting for the flooring around that area since the flooring now carries some lateral dynamic load. I did however mount my EO2 mounts to the rack. They have to hold the huge 1730 cases. (I normally only put light things in the cases, but they can hold quite a bit.)
I looked back at your rack photo. Looks like yours has no bottom and is bolted through the flooring. I like that better. I assume mine will hold water in rain. Probably end up drilling holes in them at some point, otherwise I think they will rust like mad.
Where did you cut in the flooring? can't even tell. I can see flooring in the middle of your jerry can holders.
