The furnace may have an LPG leak, or the burner may be out of adjustment, or it may need gaskets.
The combustion chamber may also have a hole in it, which means you would have to replace the furnace.
under any circumstances, use your furnace again.
To be safe, it must be removed from the trailer, and taken apart on a bench, to find out the real problem.
Since the exact cause of the smell is not known at this time, you are dealing with a possible explosive hazard, until repairs are made.
Furnaces should be removed every 5 years or so, and bench examined.
