Roll up Tonneau + T-Slot recommendation

Hi I recently purchased RollNlock (XT-Series) tonneau with t-Slot. There were a few quality/shipping issues so I returned it. Actually both first and second products were damaged. I saw threads in TW about this product shipping issue. Overall, I wasn't happy about taking good chunk of cargo space with the casing.
Then I start look for a roll-up cover but hard to find with t-Slot version. It's obvious, not able to find one because the cover goes on top/side of the cargo bed...

So my question to you is does anyone know:
1. Roll up cover with t-slot exist?
2. Any modification for the Taco's bed-top ABS liner for T-Slot compatible or something else I am missing...

Thanks for your intel/recommendations.

Thanks for your suggestion! I checked it and it seems near 10"x 10" canister and it seems big.
