I have these liners as well and can attest that they are really good. There is no movement or shifting. They are locked in place! I like them a lot so far. This week I’ve hauled 8’ 2”x4”’s, and my kids bikes/scooters to the park! Not exactly running it like a farm truck but it’s meeting all my needs for sure.Floor mats showed up today - really happy with these SmartLiner mats. The fit is perfect, they snap in to the factory hardware in the front, and they have a really nice raised lip all around to catch any spills that I'm sure my 3 year old will present.
