First you need to confirm you can flip them. Simply look and see if your axles are mounted above or below the leaf springs. I am going to guess that they are already below as both my Eagle units have been below from the factory. If that is the case then you might be able to adjust the spring mounting holes down equally which you should have the dealer do to get this unit riding right on your TV.
Yes your tail seems low and some airbags, timbrens or a load leaf would solve that issue. Remember this unit is dry and when you start loading your stuff in it plus any cargo in the TV your going to keep sagging. With a squishy TV ride it's going to compound the seesaw effect on any bumpy roads and effect the steering possibly.
The easiest adjustment for bed rail clearance is the hitch. Then if the king pin can be dropped a hole (some can't), then the axles on the 5th. In that order for bed rail clearance.
Now after you have the proper bed clearance and if it riding nose high your only option is the 5th axles. You could go with spacers on the axles to achieve the height you require for level as some have done on this forum. I am going to guess based on the photos somewhere in the 3" range to get it close enough. I would not go any more on spacers than that personally as you will decrease your stability IMHO.
Finally I think you on the right path with the sidewinder instead of the extension.
