bed liners

After having a plastic drop-in liner in a couple of pickups, that will never happen again. My experience is that they vibrate and make noise, they allow water to get in under it and stay there, they rub off paint and cause rust. If you want to put something in there to protect the bed, consider one of the spray in liners like Line-X or RhinoLiner.

I toke mine off for different reasons ,it is very slipery, the movement scratches the metal bed,
it takes space that you need to slide your camper in the bed, in my case I have about 1/2 in. Spare on each side.
I added a rubbert mat that I bought at an auto part store for about $80.00
I put a electrical white tape in the center and put a small black piece in the middle front of the camper to help backing straight

I think the point is that drop in bed liners are extremely slick. If you have a rubber mat on top, you should be good. Worst case is you break the drop in bed liner.

thanks forest! i hope you and i are not the only ones...pete

All I can say is I have had a plastic drop-in bed liner in my truck since the mid 1990's and can't point to a single issue that has been caused by it. I will admit that the camper shifts more than it probably would without it, but once it is snugged against the front wall of the bed, it stays put.

I also use Totklift tie-downs.
