Thin RTT

At the risk of bringing up a beaten to death topic, I'm looking for a hardshell RTT. The crux is that it needs to be relatively thin due to garage height constraints. I need something around 5" thick or less. I've only been able to find the Openroad Peakroof LT. It seems to have all the features I'm looking for and the price isn't astronomical. The question is, does anyone know of a similar hardshell RTT that comes in around that thickness?

I saw GFC made a superlite a few years ago, but they don't offer it anymore.
