Thanks for the reply
Yes...had to go back to my salesman, who had to go back to the RV Mechanics to determine exactly where it was and how to get at it. They were just starting to get people bringing in their units for winterization in the shop.
As you indicate, the lower storage compartment panel had to be removed. Managed to get it winterized before we froze up for winter. Not much room to work but after removing the normal water pump intake tube, I rigged up screw-on plastic elbow and long clear tube to draw the antifreeze from the plumbing antifreeze bottle from inside the storage compartment. Worked slick! After re-attaching the normal water intake hose, I left my elbow and tube kit in the pump area for next years winterization.
Interesting how there is no mention or pictures related to the location of the water pump in the owners manual?????
