I have looked around but I cannot determine the best course of action to take it change the filter.
It is located on driver side in the rear directly behind the condenser coil and above the exhaust.
Hope someone can steer me in right direction so I can get this changed.
Thanks in advance.

Welcome to the forum. Glad to have another happy RVer on board.
The post about going to Gafney, SC is great. Your rig could benefit from a 'chassis' tuneup. The Freightliner Oasis service center techs would tighten the chassis bolts, adjust the break slack adjuster, replace the filter on the air pump, replace the transmission filters... all for a fee of course.
Doing your air filter yourself is a good thing. The operators manual says to change it ever 2 years. Great for a commercial truck putting many miles on a year. Not cost effective for us RVers.
Air filters have a shelf and usage life according to a reply I got back from Raycor many years ago. The shelf life or warehouse life is short. About 3 years as I recall. (Don't hold me on this.) But, service life is 7 years because the changing environment is good for the materials the filters are made of.
When you do the change out be certain to avoid getting any dirt, even dust, in the duct tube going to the turbo. Clean the couplings well before removing. If they are damp when you separate the boot that is okay. It may not be easy to get to. I gain access to my filter through the last bay door. Makes it easy for me.
Hope this all helps a bit in your situation.
