had a c4 ladder and loved how modular it was (you can bolt anything you want to it just by going to home depot), but wouldn't fit w/ my rear bumper/tire carrier.
Changed it to a gobi ladder, and while i don't love it sometimes keeping it simple and sticking to the tried and true is not a bad way to go. Why i don't love it, is that i cant just go to home depot to bolt things to it. You have to buy expensive mounts.
so note to everyone, if you EVER plan on getting a rear bumper with tire carrier, stick with gobi.
