Long story short, I am on the road in the DC area but had to check into a
hotel tonight rather than a campground a planned (traveling with grandson)
because of a failed filler valve.

What's the best place to look for one? What, if anything beside a wrench
and teflon tape, is involved in replacing it? Probably can't get to it on
this trip but even so I would like to go ahead and source a replacement.
Let me know if this is a common item at a camping store. I have never had
any trouble with it.

Thanks in advance,

Jim
