Hardshell expanding Rooftop Tent, that fits over the short bed?

I've been looking at rooftop tents for a while. I really like the hard top designs but haven't been able to find one that fits how I want it to. I like the ikamper skycamp http://www.ikamper.com/ because of its expandable side but the dimensions would still stick out over the back of the bed.

My goal is to have the relentless fab bars to mount the tent to, but want the tent to be the same height as the top of the bed closed and not overhang on either side or over the back. In order to have a sleepable area though, it would have to expand similar to that ikamper.

Anyone know of any other tent models I could look at? It seems I may be stuck going the soft type that's more of a square when it's folded up.

 

I saw this video of the ikamper last week. I like it. I think it would be perfect for what my wife and I want to do. Having the storage of the bed while still having a place to sleep off of the ground would be awesome. Due to a tight budget, it looks like I will just be building a sleeping platform for inside of the shell.
