Which Tonneaus 100% perfect fit Rambox

[Coach_Larry]

Just picked up my truck. Looking for trifold (hopefully), and am getting mixed signals about Fitmemt. Is there a list of covers that are known fits for 2500 with Ramboxes? Need Rambox doors to stay open. Truck is 2500 mega with six-four. Here’s the beast.

I have a mega with ramboxes and opted for the factory cover - it fits and seals well for me so far, but I've just gotten it so no idea about long-term. I know some have complained about its durability in other threads.
