I was think about that, clearing the tire and ladder but I saw several pictures and videos with Jeep Wranglers with the spare on and the bike cleared. I'm worried about it snapping off. My D2 has the factory air suspension so I figure it will self level.
I wouldn’t be worried about the weight - the tongue weight rating is 550 lbs, so you should be well under that. I have one of those Harbor Freight tow hitch carriers (not the bike specific one) and I’ve overloaded it with all sorts of stuff and it took it like a champ. For your setup, I’d only be worried about clearing the tire with the bike on the rack and the fact that your rear door becomes useless with the bike on there, since the bike is in the way
