Christmas gift for FIL living in camper

Hi!

My father in law has been living in his camper since this spring. He has done some traveling , and staying in a campground close to our house when he is in town (Ohio). He will be leaving town to travel in mid-December, mostly Florida for the winter.

Looking for a good Christmas gift for him that would be useful for him in the camper that he doesn’t already have, and wouldn’t have thought of. Hopefully something that won’t break the bank.

Thanks!
