What's the best way to set up oxygen therapy equipment in an RV?

We recently received the following inquiry from Freda K. Do any of you have suggestions which can help her and others requiring oxygen therapy travel easier and safer in their RVs with their equipment?

Dear RV Travel, 
 
I think as our RVing membership ages, more and more folks need supplemental oxygen to maintain a quality lifestyle. But trying to find good information on how the adventurous manage concentrators and oxygen tanks is very limited, especially for those requiring more O2 than the nice little portable concentrators can provide. Information on how to set up an RV for traveling with O2 is just not out there -- like where and how to secure the equipment, including a large concentrator, oxygen tanks for use while driving, a liquid oxygen tank and spare tanks. I am sure if more people knew how to travel in an RV with their oxygen, theirs lives would improve greatly. 

Thank you,
Freda K.
