Adding washer/dryer difficult?

[Ryan Wright]

Hi folks,

I've been thinking about picking up a PT-40 for awhile with the
intention of living in it. As a result, the washer/dryer combo is a
necessity - and I don't want it in the cargo bay, I'd like it up in
the coach.

Thing is, I've seen several nice coaches for sale that either do not
have this option, or have it in the cargo bay. My questions are:

1. How difficult/expensive would this be to add to a coach that didn't have it?
2. How difficult/expensive to move one from the cargo bay?
3. How useful is this washer/dryer unit, anyway? Does it typically work well?

Thank you for your assistance.
