This is beginning to sound like a soap opera. Since I don't want to leave my readers hanging, I will tell you some good news.
I went to the DMV and told a very nice woman about what happened. The man I purchased the RV from never registered it in his own name. It had been smogged in September 2006 and the registration is good until October 2007. Whatever happened to the missing tailpipe must have occurred after the owners sold it on eBay. The woman started the paperwork and accepted everything I had downloaded and printed from their website including the bill of sale. Now I have 30 days to have the RV smogged, and return to the DMV to pay the taxes and fees. I'm leaving on July 3 or 4 so that gives me two weeks to have everything done.
The refrigerator works on electric. The water pump works. The new microwave works.
Tomorrow morning, a gentleman who owns a company with a crew who cleans and waxes RVs will remove the remains (nest, droppings) of the previous rodent residents, clean the cabinets and drawers, and shampoo the carpet. My friend Andrea and I will purchase curtains and bedding on Friday. The bedroom has three windows: one has a broken blind, one has a sheet over it and the third has neither curtain nor curtain rod. We will move everything to the new RV. Meanwhile, my friend Rick will install a new ignition switch so I don't have to worry about the only plastic key snapping off in the lock. Then I'll find a muffler/tailpipe shop that can handle an RV to install the tailpipe I need. After that, the smog inspection.
When everything necessary is completed, I will drive the RV locally to be sure the gas filter problem has been solved. It's definitely time to have some fun!
