Issue number two:
There is NO access port in the bottom of the water bay. Well I fixed that. In the photo below I used a 3.5 in hole saw and a simple sewer connection to "create" an access port. Three things must be placed in this port, the "city" water hose, the flush hose, and the coax if using the campground television stations. Using this access port allows us to close the compartment door when fully hooked up at the camp ground. The cap for the access port is screwed in from the bottom. Two bolts are used to keep the port itself from falling out.
