For camp work, yes. A fixed blade has no pivot to fill with dirt and no lock to fail, and a full tang survives batoning and light prying that would damage a folder. A folder is the better everyday carry; camp is where the fixed blade earns its bulk.
Splitting kindling, making feather sticks, food prep on a log, cutting cordage with cold hands. Several of those apply force in ways a pivot and lock were not designed for.
A full tang fixed blade around four inches covers all of it. See choosing a first camp knife.
It is lighter, it disappears in a pocket, and it does not need a sheath or a belt. For a day hike or car camping with a saw and an axe already packed, a good folder is genuinely sufficient.
What it should not do is get batoned. See batoning with a folder.
Carry both if weight allows: a folder in the pocket for everyday cutting and a fixed blade in the pack for camp work. They cost little together and they do not overlap much.
And add a folding saw before you add a bigger knife.
