Camper / Bed Alignment Products - Do they exist?

I think adjusting tie downs has big impact on camper movement.
On old truck I did not have any mat, yet with the holder I pictured the camper never moved on the paint.
But lately checking ebay listing, I run into camper sitting on F450.
When my front tie-downs are mounted close behind the cabin, the F450 had them like 2 feet behind, what made the fastguns holding vertically only.
Closer look show that the camper had nylon ratchet straps installed from rear camper brackets to front of the bed.
