Okay, so no wheel chocks then in the 9 foot garage, but that stinks got it.
"Ride on -step off" wheel chocks makes loading so much easier.
This is what I do - I don't recommend it for anyone else but just an idea.
I no longer bolt my chocks down.
I started with BikePro chocks, the real ones, not the hf ripoff copies.
I have 3 plates bolted to the floor of my motorcycle trailer. They work well and I never bothered to change them out.
On my toy hauler (5th wheel) I started with extra BikePro plates bolted to the floor.
I bought a Condor chock and then used the included trailer mount kit and bolted that to the floor.
After a couple of uses I removed the floor plate and just use the Condor not bolted down. A block of wood or something similar at the front to just keep it from sliding forward is all that is needed if strapped down properly.
I have since bought a second Condor for the house garage and to use if needed in the toy hauler.
Whatever you do, if you have a bike with a removable tourpak, make sure the tourpak is on when setting the chocks and make sure you have clearance on the ramp.
