Will this combination work without modifications? I don't want to add the ladder only to find that it hits the rack without fully opening the rear hatch.
Measure back from the rearmost point of your Frontrunner rack to the spoiler with the hatch open. Then find somebody on here with a Gobi ladder and ask them to measure how far forward their ladder extends past the spoiler with the hatch open. While your at it ask the guy with the Baja ladder to measure his while he's installing it.
