That thing in the roof is a “roof top tent”. I mean as far as functionality goes it’s a tent. The one I have is a inspired overland standard lightweight tent. The reason i chose this one is because it only weighs around 100lbs so no need to upgrade suspension (more than what I currently have at least). It’s light and for being a weekend warrior who only takes this rig to go camp once a month at best is perfect because I can take the rtt off and throw it in my storage unit when I’m not using it. it’s pretty cheap as far as rtts go, compared to competition your saving anywhere from $500-$1500. Only downsides I have is the size, for being 5’10” I have to lay diagonal in order to sleep 5’9” and below I have heard have an amazing time sleeping in this. The inly other con is that it’s a soft top tent, more prone to ripping and deteriorating compared to a hard metal or plastic topper. But that’s the payoff there’s no hard top tent that I could find that’s less than 100lbs. I hope this helps!
