Leaning while parked and the slide out in, that is a result of weak worn out springs at the axles. Leaning only while driving around turns would be the stabilizer bar bushings and links at the axles worn out, the springs worn out, or the shocks worn out. Leaning with the slide out, out, and the leveling jacks down, but still leaning. That is going to be a concern with the camper to frame bushings worn out.
You want a excellent 5 star answer & I would like to be rated the same for providing it. Consider I don't know your skill level & I can't see, smell, hear, or touch the vehicle. It may take a few back and forth replies. Try your best to respond with good detail so I can do the same. I normally log in at 3pm and work late. A rating is required. Your rating me, what I type. I am not an employee of this website, nor have control over the fees or the time it took to get a response. If you rate negative or not at all you still paid, but I get nothing. I want you pleased with me and my efforts, so let me know if your experience here has come up short.
