It would seem that these two are not compatible unless I'm doing something wrong. I had the Instatrunk installed, then added TrailMax™ II Fold & Tumble Rear seat because I wanted the head rests for my daughter's safety.
You would think since they are both made by Bestop it would work. At least I did…. and I can't find anywhere that says it doesn't. It would have been nice to know ahead of time. I like the trunk…. guess I'm out the $150.
