That looks awesome man, nice combo for sure. When looking into levelling, I suggest the Bilstien 5100 adjustables. You will love the ride quality for sure.. With installing the levelling kit, maybe look into airbags for the back for when you haul your trailer. Will help keep the trailer more level and not so nose high. I have mine levelled and when hauling heavy I get a little Cali Rake.. like this lol..Note this trailer also had 3 slide outs, 1 on the door side, and 2 off door.
