those cheap $20 ratcheting straps from HD or walmart just aren't real reliable.... they nylon slides too easily in the buckle.
in my (50k+ miles of load hauling, with trucks, cars, vans and trailers) I have never had a ratcheting strap slip, so I am wondering what type of strap were you using???
here are the 3 kinds I have seen:
----------------------------------------
Type 1: locking but non ratcheting
push to release cam, will hold relatively well as long as you don't put much of a load on it or have a bouncing load and you tie the tail end of the strap back onto itself. (Junk IMHO)
(there is a variation on this one where you pull the load tight then flip a cam (sort of like a chain load binder) and it locks)
personal experience: last year we helped a friend move 50mi, they have a 5x8 folding harbor freight special trailer that they haul their dirt bikes on, while I was following them when they had a bike on the trailer (behind their car) held on with 4 of these straps which were tied back onto themselves. after ~15 miles I could see the bike wobbling back and forth. the straps had come loose and they almost lost the bike. we stopped and a put a big strap (see Type 3) on the bike, problem solved.
----------------------------------------
Type 2: lightweight ratcheting
this is the type I use most, I have NEVER had the strap in one of these slip if it was ratcheted more than once. (rated for #200-1k depending on the strap)
----------------------------------------
Type 3: heavy ratcheting
I have a few of these, they are like Type 2 but heavier (rated for #10k)
----------------------------------------
I would NEVER use a Type 1 strap for anything that could come loose, at Trugreen Landcare where I worked last summer we could not use a Type 1 on anything but a tarp, a weed eater or a gas can,
I was told that for the DOT Type 1 straps do not qualify as tiedowns, and if we were pulled over and found to be using them as tiedowns we could be ticketed for having a unsecured load just as if we didn't have anything.
