Brophy on a new aluminum ford

I use Brophy clamp-on tiedowns because I never know what truck will be carrying the 1000# camper - and in that respect, they work great. But their "solidity" depends on the strength of the truck's rail - and there's a remarkable amount of flex to those; enough so that I could watch the camper lifting/rocking as we went down the highway. It also made me wonder if the "feet" on the Brophys could somehow dent the bed from the inside out if the camper pulls upward hard enough? I've not seen that happen - but then again, all our trucks have had steel sides.

If I actually owned one of those beautiful new Fords, I'd go with Torklift frame-mounted tiedowns.

PS: the Brophy stake-pocket tiedowns require holes to be drilled in the truck.
