Tiedowns are pretty specific to the year, make and model of a truck. Yeah, some tiedowns can be used across various applications, but in some cases, it might involve drilling. By and large, tiedowns are not something I would to install, remove and reinstall on a regular basis. Maybe once. To me, tiedowns are something you install and leave on and sell with the truck or remove once and sell or reinstall on the new truck--if they fit. My rear tiedowns are the drill-into-the-hitch type. Not something I would want to bother with or do multiple times to multiple vehicles. Now, the slide-into-the-hitch style, I would probably remove, keep and hopefully re-use on a different truck.
With the Happijac system, you will leave holes in the bed. IMO, that takes value away from the truck. Torklift is the only system that generally doesn't require holes to be drilled, but still would be a pain to remove and reinstall on another make/model vehicle every time someone gets the urge to buy your truck.
