First, model number please.
Keeps clicking but will not lite. What does this mean?
My gas solenoid will turn on, I hear the furnace try to start (gas and ignition), but will not stay lite? See what I mean, about saying your words.
Sail Switch, Over temp switch, Igniter/flame sensor, Gas solenoid.
You could also goto the Atwood Website and get the manual and trouble_shooting doc. You could also call the tech support line.
But if you want help on any forums, you should start by being specific about what you hear and see, please. Best I can do with the info given

Double check you propane leak detector. They need power to let the propane pass as a safe guard. Also try lighting a burner on your range and see if it lights and stays lit if that works chances are the problem is not in the propane system.

First, check the intake and exhaust ports for wasp nests, spider webs and other critter debris that might be hindering air flow. If air is restricted, the sail switch will not close the circuit to allow the gas flow.

Most attwood heater problem are do to bad connections. Remove and reconnect every spade connector on the heater to improve the connection.
