Want to RENT RV/Camper/Trailer in Portland, Oregon For Sale

My husband and I are looking to rent an rv/camper/rent trailer from July 3rd to July 6th for the St. Paul Rodeo. We are willing to barter some services (husband is a diesel mechanic, and I am an OCD cleaner) or pay, even combine options. We will provide our own insurance for the rental time, and have proof ready to show you on pick-up. We can tow a 5k load with our Jeep, and have towed/driven before. We are located in Portland, but are willing to travel to pick-up/meet for transfer anywhere from Vancouver to Banks to Woodburn areas. we can afford $20-30 per night, and will return the unit as it was offered.
We are clean, non-smoking, and there will be no pets. We can provide our own linens, and kitchen stuffs. Just need a place to sleep basically! If you have a camper sitting around and can use some extra income, let us know! Thanks!
