Help with furnace

I have a 85 13 foot sunline trailer, it has a furnace, the pilot light will stat lite for a few seconds then goes out, if you take the pilot and thermocouple out light it will stay on, I have blown out the air intake from the outside and hooked up a shop vac to suck out anything. fan works thermostat seems to work, cooking stove works fine. If anyone could shed some light would be great.

Bit confused on that one I didn't think an 85 was old enough to have a pilot light. Is this something you actually have to light with a match?

No Sir it has a piezo type spark ignitor and it is sparking just fine, I do not have a owners manual and just going by what I know, it is just like lightning any other gas appliance, turn the knob to pilot push in and hold press the ignitor till it lights, once the thermocouple is hot you release the know and turn it to the on position set the thermostat and you have heat

OK kind of sounds like a bad thermocouple. Model number?
