You are probably right in the ball park on the cost estimate for you remodel. I just restored a 1989 Class A Bounder. Did not do a lot inside other than clean, LED's, Flat screen TV's front and back. I want to restuff the sofa, that's next on my list. My main concern was to make it road worthy. I replace all the fuel pumps that meant dropping the fuel tank. Replaced: Power steering pump and hoses, muffler, shocks, air bags, tires, headlites, radiator recovery tank, battery isolater switchs, new batteries X 3, serviced the transmission, oil change for engine, rebuilt the carburator,New brakes in the front, overhauled the Onan generator at the tune or $650.00. After all that I have $12.67 left in my RV fund. Wow, that's a lot. Now I need to take it out and have fun.
