Would you believe that you can pull the door handle off when shutting the door? It happened after I turned the passenger seat. The GM dealer said they could only supply a complete inside of the door, for some astronomical sum of money, so my DW had to ride without an arm rest for many miles. Fortunately NewGMParts.com came to the rescue and shipped the two pieces ($45) of the door handle to my son's home in Iowa for $8 shipping vs $52 to Canada. The new passenger door handle was installed today, using the old fittings which I kept (just in case they were not supplied). Peace reigns once more.
I had some "Drain J" left over from the stick house. Bought it at Canadian Tire. It is used for cleaning waste pipes and is safe for for septic tanks. So I put some in the black tank and some in the grey tank along with some water. I allowed some of the solution to sit overnight in the macerator. Now the macerator runs very quietly and smoothly while working and only when it runs out of fluid can you hear it.
