Basic Questions 2002 TM 3023

Good day,

I have recently purchased a used 2002 TM 3023. This is the first weekend I have had time to spend cleaniing and organizing the TM 3023.
I have a couple very basic questions:
..Where is the fuse box(s) located?
..The beds...in the extremity corners of both rear and forward beds I can see daylight. The corners are not sealing correctly...is this normal ? If not normal is there any fixes?
..Has anybody experianced insect ingression though the seals of the TM.
..During storage (1 month - 2 months) any special proceedures to follow?.
..During storage how do I prevent interior moisture problems (mildrew, mold etc).

Thank you

Brgds
