FiberForce bed topper. 64 inches wide x 81 inches long x 24 inches tall. Gun metal gray (or silver or whatever you want to call it). Don't ask what it was on. Measure your truck bed. Near Mossy Head on Hwy. 90. Free to a fellow fisherman. Bring someone to help you put it on and your own clamps (some parts stores have clamp kits) or vice grips.
I googled it. So, that's your camper that looks brand new ? If so, I'll take it.
If not, how about some kind of description as to condition so somebody doesn't drive all the way to Mossy Head just to clean junk out of your yard ?
