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.
