Is this ok

2021 351MR around 4000 miles. Was under it greasing spring bushings and notice springs almost flat on kitchen side only, I know that side is heavier and it's never set level since new. This picture is with trailer mostly unloaded. 100lbs in garage and pot's, pan's and dishes. 1/2 tank in generator. Other gas tank, black tank and grey tank empty. No clothes or groceries in pantry or fridge. Living room side still has some arch. Was wondering if other 351's look the same.
1st and 2nd pic. is kitchen slide
