H3T How tough is the factory plastic bedliner on the T?

[SedonaBound]

I need to get a couple cu. yards of small (1-2") landscaping rock for a project but don't know if I should protect the bed in my H3T with more than a plastic tarp. The stone yard will drop the rock into the bed with a front loader. The liner's already got dings and scratches but I don't want to crack it. If need be, I can cut a sheet of plywood to cover. I'd rather make several trips than pay $80 for a delivery and then have it all dumped in one spot.

I think its gona do alot of damage esp when the rocks are dropped lile that! Also the body should be protected as sometimes the rocks will pile up and fall out (possibly damaging the body as they do) or an unintentional driver error.

I'll have a tarp protecting the sides while loading. I'll be maxxed out on weight (1000#) before the bed is 1/4 filled so overflow isn't a worry. I guess I'll make hinged "liner for the liner" out of 5/8 ply; bottom and four sides.
