Spent about 7 days sleeping with the Mrs in the back of the truck when we were in Green Mountain National Forest. If it's just you and two dogs, I think you'd be fine with a drawer system.
What did I do to her? First, I did what you see below in the videos. Then I spent the better part of an hour wrestling with a power washer to get her clean ?
Yes, but it is tire/wheel specific. My AT3Ws rubbed, but so, so slightly. I'd wager after 10K miles on them they wouldn't rub anymore.
I know people running 33s on different wheels/tires that experienced zero rub at full lock.
