HELP - Tonno Pro Lo-Roll Cover Installation

I originally posted this another forum but this one may be more appropriate.

I just recently purchased a Tonno Pro Lo-Roll cover for my 2013 Tacoma DCSB (with utility track). The one I received is the correct one for this truck according to the vendor.

I am having trouble with the install. I don't know if its the product not fitting correctly or if its just me but I'm starting to get quite frustrated to the point I want to start slinging parts across the yard. The instructions aren't very clear and there are no videos for Tacoma install.

If anyone has this exact tonno cover on their 2nd gen can you PLEASE take a few pics of how the frames mate up to the bed rail (top/side pics) and underside where the track/mounting brackets attach (specifically around the notches cut out by Tonno Pro and where they are in relation to the other mounting holes).

I've tried mounting the frames several ways and nothing seems to fit right. If I mount it one way its too narrow for the roll cover. If I mount it like the instructions say then there are 3 huge gaps caused by cut out notches that will let water into my bed.

Again, if anyone can please post pics of how the bracket/frame/track connection looks I'd really appreciate it.

TonnoPro's website has videos but nothing specific to the way the Tacoma install is.

Thank you in advance.

 

I have the lo roll. Ill try to get pics later.
But i will say this. Do not expect this to be 100% water tight, it is not. There will always be a gap in the corners based on my experience which allow water in.
