"I sent Larry and Dale emails and asked what year their 5ers are if its that important to you to know."
Its not that important to know just thought you would know did not mean to cause you to have to send emails to anybody sorry.
" The fact that others here and my 5er proves your blanket statement wrong that all have 2 gray tanks."
You and others do no have to prove my blanket statement wrong it was wrong. I will be very careful if I make any further posts to not make any blanket statements.
" Yes all 3 of ours have the toilet and shower and a sink on the upper level."
Do you know if there is a check valve in the drain from the kitchen sink that prevents back flow if the grey tank is full and water is drained in shower and sink on upper level. Just asking out of curiosity don't go to any trouble to find out if you know that's fine if not just disregard
"You shouldn't take this wrong as I was not putting you down just correcting a wrong statement for everyone else reading the post."
I have corrected the statement so others will not be led into believing that wrong information if they read the post and not your correction.
