hot air heater filter

I have a 97 mountain aire dp that i recently purchased. I would like to know where the return air is on the hot air heating system [propane] and are there filters anywhere that should be changed. Never saw a hot air furnace without a return air but I sure can't seem to find one on this unit! Any ideas would be appreciated!

Most of the units have the furnace return air right at the furnace. Some have a foam mesh filter, some do not.
