Towinng with a full tank?

Kos is a newbie... he may be new to forums also.  He needs to understand that nearly all threads that are started on forums can take a turn.  Discussions in general, just like when you are talking to people face-to-face, almost always sway with the conversation.  That's what makes us human.  You start off talking about one thing, then something you say elicits a response that's off the original topic.  There's no rule or law that says you can't use the original topic to ask or respond to other things that are said.  No apology necessary.  Thanks for your help.

I call it kidnapping a thread. I suggest to open a new thread for this discussion.

Back to  the original issue.
I do not like the placement of the freshwater tank at all. It makes a real difference towing the Pod with an full or empty tank. I have no idea why they placed it behind of the axle.

+2.  Very noticeable in my 177.

It is a 1/2" NPT cap. OK to loosen with pliers. Doesn't need to be that tight. I replaced mine with a 1/2" NPT valve I got from Lowes. No more taking the cap off, just move the valve to drain. The members who talk most about towing are those that have a rear mounted FW tank, not sure what you have. I have a 178.

I have a 180, 2017.5.  I have a Centerline WDH.  Have only pulled it once with my 2004 Titan.
