Lanterns are always nice. LED's are the way to go as the batteries last 5-10 times as long in those. Variety of sizes and price ranges.
Fireplace tools like a log grabber to manipulate the firewood in the campfire are nice and something most of us do with a strong limb or "stirring stick" we find laying around. Friend of mine left his with me when he came camping one time and I have not remembered to take it back to him yet. Maybe in the fall when he needs it for his fireplace.
We like anything that has a camping theme to it. Wife found some salt and pepper shakers that were shaped and painted like little travel trailers so now those are what we bring out to the picnic table for meals.
Visit a RV dealer and go in and check out their parts department. usually have plenty of useful stuff to give you some ideas.
Good Luck deciding!
