Hi folks.

Hopefully this isn't a dumb question.  or not too dumb at least.  

Our campervan needs a good external clean, but it's 3 m high.

"she who must be obeyed" will not allow me to get up on the roof with a pressure washer!   Sound advice I reckon.

Are there any places in Western Sydney where I could get it washed?

Will a truck wash blast the decals off!

What sort of wash facility should I be looking for?

Recommendations welcome.
