I just plan on doing regular towing uhaul type towing. Mostly 5x9 trailer or a motorcycle trailer. I actually don't know a lot about towing but is it a good idea to get an adjustable hitch? I am not sure how the air suspension is going to settle and I don't want to be without the proper hitch.

 

I don't know a lot about towing either but my stock LR3 pulls various-sized U-Haul trailers without any adjustments required. Also pulled a 21' 5000+ lb boat without issue. if you have a lift you could get a 2" (or whatever size lift you have) drop hitch to compensate. U-Haul sells all of that too so you could make the adjustment on the fly in the event you needed to. You should be fine.
