Don, do you say the same about car manufacturers? BMW bought RR and probably share some components. BMW's are made in Germany and RR in England. My Land Rover is owned by the Indian Company Tata Motors but it's still made in England. Bentley is owned by Volkswagen, things change in life but they can still keep the brands separate. We'll see how well they do.
Life moves on. Things are improved. There will always be die-hard people for every manufacturer whether it be car/boat/RV. I believe Monaco's will still be Monaco's even though the Roadmaster chassis as been changed/improved and is not an exact replica of the old Roadmaster chassis.
All parts seem to go obsolete. My '64 Rolls Royce needed a new power steering gear box.... Rolls Royce is still in business but they don't make a '64 power steering gear box anymore (shock). So, they had to rebuild the one that I have at almost $5,000. It happens to most everything if you keep it long enough.
If Allied keeps bringing out new product on the Monaco line and makes them different than Fleetwood by the looks/amenities/design, I think they can make a go of it and Monaco will have their own identity.
I have gear-head friends that just went nuts when Ford bought Jaguar, that was the end of Jaguar for them. Ford improved Jaguar where they would actually run without breaking down. They got rid of the Lucas wiring, etc. Jaguars actually became very reliable vehicles after 1995.
