Wanted: Rental Trailer for Weiser Fiddle Contest - $1 (Seattle)

I am wanting to rent a travel trailer or fifth wheel trailer to camp in for the National Oldtime Fiddle Contest in Weiser for June 14 to 24.
We would need it to be set up at the campground behind the high school in our designated campsite.
We would like something comfortable, trailer or fifth wheel with a kitchen, bathroom, refrigerator between 22 and 30 feet that was filled with a full water tank when delivered, set up and leveled ready to be used.
Then picked up from the campground when we have left.
We will not have a tow vehicle at the campsite.
We have attended the festival yearly since the mid 70’s and just sold our trailer and truck thus looking for a rental.
Contact me with questions and details.
Thanks!
