Furnace not lighting

We have a 1987 Shasta Revere and are trying to figure out how everything works. We are having problems with the furnace lighting. We have followed all the instructions and it tries to ignite and you can see it through the little window but it won't stay lit.
Does anyone know what the reason for that could be? It is a suburban furnace.

Low propane pressure , bad ground on the propane solenoid , burner grill rusted out. Can you get a model number off the furnace , maybe we can find a complete troubleshooting guide.

There's a little temperature probe that is positioned such that its right in the flame, it's called a thermocouple. It is connected via a small tube to the gas control valve. When the thermocouple reaches a certain temperature it pushes a contact in the gas valve telling it the flame is burning and not just pumping the trailer full of propane, and that it's ok to let the propane flow.

After they've sat dormant for a while a thermocouple often becomes weak or 'fussy' and seems to want more heat than usual. Often you can fool it by heating it with a small propane torch. Sometimes after a few cycles like this they start working, sometimes they need to be replaced. They're not much money.

Been there and done that. Mine ended up being a combination of the burner grill being rusted not getting proper gas flow and flame to the thermocouple and the thermocouple placement and probe proximity needed tweaked. Works like a charm now. I would concentrate on those two items if all connections and wiring are solid.
