On my leveling platform, I use these to tie down loads. They're pretty low profile, never had an issue sliding stuff over them. Of course they're not as flexible as using tracks, but with a few carefully chosen points, I've never found that I haven't had a tie down point I couldn't use.

and these in the mounting points as needed:

As far as securing the platform goes, I usually strap stuff using both the on platform points and the factory tie down locations to secure the load and platform to the truck itself. I'm sure there are better ways to do it though.
