we have tried a lot of different wheel chock systems, the latest being the lock and load- not a fan!! Lots of slop and wild have a lot of metal shavings under the foot pegs. Our current setup is the Bolt it on. It’s fully customizable and can do big bikes all the way to mountain bikes. It’s a rad system!! Install is quick and easy. We bought the angled mounts to load 3 bikes in our van. It’s slick!! Scott is the designer and owners name, he’ll treat ya good!For the most part I used 1/4 x 20 stainless with flats , and nylock nuts anywhere I could contort a hand or tool in on the backside.
Anywhere there was no access I used riv nut inserts.
The Lock N Load's are a lot like the Baxley type chalks I have but my only issue is once you start angling bikes in they take up a lot of floor space and you are unable to get the bikes exactly where you want them. I used them exclusively in my old van and loved them.
That mini bulkhead also has removed any kind of flex the van seemed to have or oil can type noises from the vast sheet metal panels.
