I think your ride height is fine the way it is. That being said, you do have a slight squat in the TV, and the trailer is the slightest bit high in front. So, it isn’t broke but, a lift in the axles and airbags would do the trick and normalize any irregularity. Just don’t sacrifice stability on the trailer with the spacers.
My truck has factory air ride. So, loaded, the truck levels to preloaded height (with the natural rake) and I have an alternate ride height option if need be (no squat but level). Look for bags you can adjust yourself.
