From what I could tell, the Brophy clamp-on HSSF ones should be OK for a light camper (4WC or ATC), but anything heavier + dirt road usage = may not be strong enough.
I went with Happijac tie-downs, with the spring-loaded front turnbuckles + rubber cushioned rear turnbuckles. We mostly camp off dirt roads, and there's a lot of flex & bouncing around with the loaded up camper. The Happijac tie-down bar (in the front of the truck bed) has 2 adjustable bumps that keep the camper centered in the truck bed and don't let it shift side-to-side when offroad. I have very little side-to-side clearance between my camper and wheel wells on the truck, so I need the camper to be almost perfectly centered.
The other main tie-down system out there is Torklift, which is a lot burlier and heavier than Happijac, and about twice the price. It also hangs down fairly low. I think the Torklift system is a good choice for a big hardside camper, e.g., something with a slideout, mounted on a dually. For smaller/lighter campers, it's overkill.
