I have the Large
Solo stove and use it for a mini smokeless campfire. Since I have a small truck camper with limited space it works well for me. I just cut up scrap lumber into small chunks 1-2" X 3-5" and store them in plastic pails with lids. I carry the stove and enough fuel for a couple of fires in one and if it is a longer trip I slide a second one in. They store in the wheel well storage. There is always small sticks and stuff in the camping area to supplement.
It works great, maybe a couple of minutes of smoke till the gasifier kicks in then very clean burning. I have used it on my wood deck with just a pizza pan upside down under it with no problems.
A friend has the Big Campfire model and loves it.
