New with the aluminum bed stuff.
Last truck had the steel bed and I linex'd it, has held up great. Just a couple small dents at the wheel wells where something tipped over and dented the hump all other areas are dent free.
Was planning on doing linex with the new one. My concern is with on how easily is this bed going to dent whether its the floor or sides vs the old steel versions even if its linex'd.
Is it much of a concern, should I be doing something different ??

Go to a dealer and jump in the bed of an aluminum truck; jump up and down....and see for yourself.

I recently scuffed and Hurculined the bed of my new truck; it seems just as solid as my old all-steel Chevy.

One difference I noticed about the bed on my 2018; it's a separate component from the side walls; I can see between the lines where the side walls and bed meets (where my old Chevy is one unit). My opinion of this design is that a dent on one component might prevent the energy from transferring to other components... perhaps preventing warping.

Jump in and jump on it!

 

I linex'd the bed on my 2018 Super Duty 8ft bed about 7 months ago and it is holding up great. Been tossing a lot of construction debris into it and so far no dents that I can see.

 

I scuffed mine up and did a Raptor liner self spray back in Sept. 2017. I also had a rubber bed mat from a previous truck so I threw that in also. So far, so good.

 

Had my 2017 linex' d 10 months ago not long after i bought my truck. I've hauled alot of stuff in my bed since i've had my truck and the bed has held up great.

 

I have the factory Ford spray liner in mine. Seems great but then my truck mostly pulls a trailer and I seldom have anything in the bed.
