Selfishly, I hope you make it back to Moab in October. Have fun, whatever you decide.
Sometimes DH drives me nuts. He would love to pack up the rig, pull to the end of the driveway and then decide to turn right or left. I'm fine with spontaneity, but he's a terrible navigator, which means I get the job by default. Hard to plan food, gear, ROUTE, etc. if you don't know where the fuck you're going. That's part of why the Moab Meetup is so much fun. Thanks to a tip from
@lhamo (IIRC), we've had our campsite reservations since Black Friday, 2022! Squee!!
Have fun, which ever way you go.
PS. Loved the rental tips. I also use Hertz the way you do. I'm a Gold Member from my working days, so I used to get deal offers and upgrades on the regular. I need to start surfing their site more. In addition to your excellent list, I have had good results using Auto Slash. Sometimes the best Hertz price is through them. Add your Hertz# to the reservation and get all the Hertz perks.
