Any changes or suggestions or ‘re-working’ of my idea to make it work OR work better would be appreciated.
If I have a truck like this:
(I could either remove the tool box, or leave the tailgate down if I need more length in the truck bed.)

Could I attach one of these to that metal thing behind the cab window?

Up one of these or something similar:

And secure it in a chock like this

WOULD IT WORK? Would I be able to load/unload my bike by myself (female lightweight)?
Suggestions on ramps, winches, chocks, tie downs are appreciated.
Thanks.
