FF17 Questions

hello,

new member here, I recently acquired a 1988 FF17 for a move. I have changed radiator fluid, oil, belts and tires. I was curious if anyone can tell me some of the things to watch for or any known issues I have not addressed?
I do not have any maintenance history, only what the current owner could tell me. it sat since 9/2022, fires up fine, but has a battery drain which an owner along the way addressed with a battery tender mounted to the battery box.

thanks in advance for any advice!
