"Rick" (the car) was a good travel partner. With "Rick", we were able to see many beaches of Maui at our own pace. We did have an issue with "Rick". There was a rusted hole in the rear that caused a leak when it rained. It apparently rains often on the east-side of the island any time of the year. The leak soaked a portion of the bed which made it uncomfortable to sleep and also damaged our belongings. Christine compensated for the damages caused by the leak which was appreciated.
The bed wasn't the easiest to setup, but it was sufficient. The bed also wasn't the most comfortable since the pad was on the thin side.
Thinking ahead, we brought our own mosquito net/canopy to protect us from mosquitos. This allowed us to leave the windows open for airflow as we slept. Note that it gets a bit warm in the car even at night. Bringing our own mosquito net was very valuable.
For privacy and security, we found ways to cover all the windows and windshield since "Rick" doesn't come with any sunshades, curtains, or covers. We would suggest bringing something to cover the windows for more comfort.
Amenities that Christine listed were accurate and useful. The cooler bag was sufficient in keeping our food and drinks cold with the bag of ice we picked up. We had fun cooking our SPAM and eggs breakfast on the provided propane stove and camping cookware. Driving "Rick" was great and the A/C works great. We would suggest to make many stops at waterfalls to cool off and to get a bit cleaner.
When we checked out, Christine was nice enough to hold onto our luggage before our late flight out that evening. We walked to the nearby beach which was about a mile away and grabbed some lunch and shaved ice on South Kihei Road.
Note that the location of "Rick" is about a 20-min Uber/Lyft ride to the OGG Airport, so plan accordingly.
