Room for a 4 seater

you'll be fine with stock height. I have a 2007 3005 Falcon, same trailer just 4' shorter and pull with same truck, one year older. I had to raise my hitch to its highest and the trailer sits just a tad nose high clearance is just acceptable at 6-7 above bed rail. I don't tow offroad over rough terrain, just fire roads but I'm careful and not had an issue, my combination tows like a dream so never wanted to flip axles. I did consider either raising the front of the truck or dropping the rear an inch or so to get the truck level, that would add a little more bed rail clearance.
