Looks like it's coming along! About the wobble - make sure your tires are properly balanced. Carrying a TC will magnify any little suspension or tire problem you may have. As for levelling, I think the answer is a little of both. You want to make sure the camper itself is level so that your fridge works properly, of course. You also want it to appear level when you travel. This last one is largely cosmetic I suppose. Toyotas have a wee bit of front rake to them from the factory, as do most rucks these days. I have been trying to get rid of mine for a while now, and my last suspension mod, Fabtech coilovers in front, are going to allow me to finally solve the problem. I want the same clearance around all 4 tires. I just measure from the tire tread to the wheel well. Then I step back across the street and eyeball it for level.
As I said though, #1 important thing is camper itself level, for proper function. #2 thing is ride quality. You won't drive it far it it scares the life out of you, or beats you to death. #3 is appearance - does it look like it squats or anything.
Good luck, and keep it coming!
