Richard is a wonderful host. The 4runner we rented has everything you could need. We were very impressed with how clean everything was. If you require additional support for sleeping, I would bring a supplement. If you're used to backpacking, then have no worries. I would say if you're camping, be sure to get reservations ahead of time for a camping spot. COVID restrictions really make it difficult to use the usual resources. That being said, Richard will point you in the right direction and help you maximize your time on Maui. Be considerate to all and practice aloha. Cheers.
