Terry was very friendly and responsive. The van was in good condition and had all the amenities that were described. It is well thought through and features a lot of useful details.
It drives well, no complaints.
One thing to bear in mind is to check for campgrounds in advance. The number of those on Maui is extremely limited and they book out quickly. Permits for the public ones can only be obtained at certain hours on certain days at the permit office. Same scarcity applies to Haleakalā national park and the state parks.
If the van camping experience is what you are looking for, this particular one is modern and convenient :)
