Don’t want to discourage the OP but if I was looking for a unit that was accessible for older or out of shape hunters I would probably look elsewhere.
I lived and worked that area for a couple years, it’s rough. And I wouldn’t view the lack of elevation as a positive. A select few had it figured out, but even then it was far from an easy hunt.
A few pointers I can give are take extra water and fuel. An extra spare is a great idea, the roads eat tires. Not sure the dates of your hunt but that country can get dang cold for a desert. Stop and eat at Pickles Place in Arco. It’s beautiful country in its own way, I have a lot of great memories up there.
