A see some common taste here...
Looking at the same rear bumper in my garage now. Glad to hear the install was an easy one.
Also, after a fair amount of research, I too put the iKamper atop my list. I plan to haul it on a utility/camping trailer instead though. Kudos on the pulley set-up! Nice. I was envisioning something just like that, but for a carport that I still need to construct as my garage door opening will be too low...
Kudos on the build.
