I had a tricky setup on my teardrop RV, weird angles and obstacles (I didn't originally design the gas struts so this was an aftermarket project). Vigor really helped me think through the process of figuring out what I needed and replacing the parts that didn't work (the first pair of racks I got was 3 inches from closing the galley hatch). In the end I got a set that worked great. and it's truly one of the best upgrades I've ever made. No more bracing your back with 2x2 bars! It just goes up and stays there.
