Balmy Girl

I have just bought my first motor home.  I went with the nicest I could afford for the money I had available.  now I have the Talbot Express Highwayman which has a rear door.  I can fir my daughters bike in the toilet, but cannot get my bike in.  What solutions
do people have for taking  bikes when they have a rear door?
