Today we got word that the repairs are complete and we can pick the little RV up in the morning. The shop opens at 8am. Apparently the connections in the line running from the toilet to the holding tank were not sealed adequately causing some leaking. The leak was not completely contained in the well on the top of the black tank and ran down into the insulation in the belly of the RV. That is were the smell I have been hunting for was coming from. The damaged insulation has been replaced and the line has been fully sealed. The repairman also replaced the wiring harnesses on two of the four tanks. He was able to get to the black and one gray tanks to replace the wiring. The other two tanks were impossible to access without removing the underbelly, all of the tanks and a significant portion of the surrounding components. That would have taken considerably longer. I hope the black tank problems are resolved. My new motto is expect the worst so you'll be pleasantly surprised with anything better.
This evening Rob and I had a final dinner with all the kids and grand-kids. We went to a BBQ place that had great reviews and has won some awards. It was a very casual place with great staff and really good food.
Anyway, we are heading out tomorrow but still don't know what our route is. We may go directly down I95 through NYC and Washington DC or we may try to take another route and try to avoid those two big cities. I guess we'll all find out soon enough.
