I actually enjoy washing the motorhome when I have time.  I would say about half the time I wash it and the other half I pay someone.   I feel it's good exercise.  And I only use the long pole when drying.  I actually climb up on the ladder and hand wash it.   That way, I get good arm and leg exercise.  I know at some point in the future it won't be safe to get on a ladder....... hopefully, many years ahead.
It takes me about 2.5 hrs. to wash, dry and clean the wheels.   It's such a good feeling of accomplishment when it's done and I'm exhausted.  LOL!
