A big fire is nice but unless it is really cold out, you don't need a big fire to have an enjoyable evening around the fire.
I made a little fire cap because I don't have a lot of extra space in my Popup camper for firewood and we don't want to haul what might be buggy wood. In the wheel well storage area of our slide in camper I have a 5 gal pail of scrap lumber, two coffee cans full of artificial log chunks and my fire cap. That is enough fuel for an evening fire for a week. I will scrounge small twigs to supplement when available. I find that the artificial logs, I have switched to the enviro logs so we can cook a marshmallow if we want, cut into 2 or 3 inch slices make a nice base fire to then add my scraps. If you have a very small camp fire the logs have to be small, so my scraps are cut to roughly 1"X1"X4" chunks.

This was when I was experimenting with just wax logs with lava rocks over the top. Better looking fire without lava rocks and just wood chunks on top.

This is what I started with, bought at a flea market for $2. I cleaned it up painted the main part with grill paint and drilled a few holes around just outside the stainless part to get some air into the base of the fire.
Last month I picked up a couple of similar shaped caps off an English Ford but smaller. That is the next generation for next year. Even less space to store.
Been using this system for 6 years now.
