George, It would be appropriate, but would not be able to get the baster in the right position to fill the tank.
Grant, I crawled back under the coach and found a way, from the backside of the tank, to get one hand on top of the tank.
LaMonte, your mod would be nice, but I really don't want to put anymore money into the coach at this point. I have owned the coach for over 10 years and this is the first time I added fluid to the tank...hopefully it will be 10 more before I have to do it again.
UPDATE: As I said to Grant, I was able to get one hand on top of the tank and clean the cap before removing. I purchased a small funnel with a long spout which allowed the funnel to be secure while pouring the fluid. Next, I took a small bottle and began slowly fill the tank reservoir a little at at time until the warning signal stopped. I replaced the cap...tested the system and all is back to normal. Total amount of fluid used 22 ounces. Amazingly, I did not spill a single drop during the process.
I have attached four photos showing: 1. Cap before cleaning 2. Small path to get to the cap. 3. Funnel in cap before filling 4. Small container used to slowly fill the reservoir. And, while it may look like I had plenty of room due to the photographs, I actually slid my iphone into a small opening and took the photo in the blind.
Thanks to the folks at RVA systems who pulled their files on my model Beaver and told me where the tank was located and the best path to explore in refilling the system.
Thanks to the members of this forum for you suggestions, advice and expertise in fixing this problem.
Happy New Year everyone...
