I have 2004 Revolution 40C I bought in February of this year. I have done a few thing (replaced TV's, carpet with hardwoods, tires, added led's). It had 28,000 on the chassis and 100 in the new Cummins 350hp engine.. (Campingworld blew the engine before I bought it). So far I love it. If I can answer any questions please let me know.
