Getting Our Newell Coach Retail Ready

We would like to know what others would suggest we do to prepare our coach for sale?

We know that looks have a lot to do with it and we plan on getting it detailed.

We will try to sell it ourselves first, if all fails we will consign it with a RV dealer.

Should I change the oil and oil filter?

Do I need to worry about any scratches on the exterior? Should we have them touched up?

Should we get the premium wash and have it waxed too?

There is a small snag in one of the blinds, should I have it replaced?

I'm not sure how much I should put into it to get it ready?

Anything else?

Any help would be great...

Thanks!!
