In Need of an Exorcism

We have decided that my sisters' RV is under the influence of demonic possession.  This first manifested on the trip to Texas, when the outside door would suddenly burst open even though the door was securely locked.  This necessitated having her passenger lean out of the RV at 75 mph to try to close it before the cat got out.  Then, of course, the unit was flooded with black water (aka sewage) in the only place in the Northern Hemisphere where the people were a) completely unaware of the dangers of contaminated water and b) too stupid to care.  It took 7 months to get the RV repaired and my sisters had to make a quick trip to Texas in mid-summer to retrieve it - only to find out that the toilet hoses had been grouted up, the sink wasn't connected properly and the dinette seats weren't bolted down.   This required another full month of repairs in Ontario.  But the demon wasn't through with them yet....on the way to Texas they had a high-speed blowout.  But then, in Ontario, the same car developed a slow leak which was from a unique bulge in one tire.  The tire tech said he had never seen anything like it.  So - 2 tires replaced.  Then, on the way back from the repair shop, another tire on a different car they were in went flat.  Come to think of it, I also developed a flat on my car after my sister and I went for dinner.  The tech said there was a screw in it but he had never seen one go into the side of the tire like that one did.  Hmmmmm.....One could be bad luck, but 4 tires????  We need intervention.  Anyone have the phone number for the pope?
