extangTrifecta 2.0 Soft Folding Truck Bed Tonneau Cover | 92830 | Fits 2016 - 2022 Toyota Tacoma 5' 1" Bed (60.5")

Does this come with the adapter for the rail system that the tacoma has?

Does this cover leak into the bed and does it require holes drilled for drain tubes?

How much weight could it hold

i have a 2017 toyota tacoma 4x4 double cab Trd sport , i went to mesure the bed from the front to back and had 59/and a half inches, is there overlap
