If yours is like our previous RV, it was made by El Dorado Inc. They went out of business after BK in 1989ish.
The commercial bus side of the company was acquired by Thor and renamed Eldorado National:
Commercial Vehicles - Thor Industries, Inc.
Here is a bit of history from a previous employee:
El Dorado Motorhomes
