Art there trailer parks or campgrounds that allow year round camping in Hawai?

My wife thinks that there probably are, and if we found one that we could live there probably for under $600.00 per month. I say no way (I was stationed there in the Navy about 15 years ago and don’t remember them, but then I didn’t get off base that much). My plan is to live in boat, which I feel we can acquire for under 100K (after we become CRNA’s/ nurse anesthesists).

Thanks,
