Hello, I have never used an E-Track tie down except via using them in a U-Haul. They were great and I felt confident that they would hold but I didn’t install them so I’m not sure about the strength. My plan is to use them in my RV to mount a Condor Motorcycle Chock. There are lots of chocks and various methods to tie down a Harley in an RV and Condors are not cheap but the main problem I have is: under the area where I wish to mount this chock is a holding tank. I don’t want to drill too deep and puncture the tank. E-Tracks can be installed with many screws. I think I probably have 3/4 inch to at best one 1 inch of space to work with. Lastly, how strong are E-Tracks when mounted this way? Any advice would be helpful. Thanks!
