I use the same chock for lots of reasons. I think it would be great to add them as a part of the trailer package. I use them when I drop the boat & trailer, I've used them to help extend the trailer tongue, before a launch, Security on a hill. Standard equipment on the job. Hardly optional in towing. Be nice to have a holder for chocks on the trailer... I prefer the pair style. two chocks separated with a chain or rope. If that doesn't ring a bell it would look like Nunchucks but the sticks would be triangular so you could toss one in front as well as behind a tire in one motion. Bill
