Help.. backflip g2 install

Hi everyone..blakflip g2 came in the mail.. We have a few situations: 1

do I need to use the wether stripping if I have the rhino sprayed bedliner?

2. Factory rails block drainage port on the bed and the drainage hose don't fit through the port and I'm trying to avoid drilling ..any advise?




3.Is this going to be a problem?

And do I still need the wedges for this?

 

I used the weather stripping, I have the factory sprayed in bed liner. My drain tubes go through the plastic covers that are on the rear wall of the bed. I drilled a hole through the plastic and it holds the tube in it. That shouldn't be a problem the amount of water that will get through there will be handled by the drainage system. As it gets hot, it will mold to it a little more anyway. I didn't need any wedges on my MX4, but not sure about your issue.

 

Thank you @bsktball55. The dealer rhino those vents but I can still through them.
