Edit: I should point out that running water is a real game changer in van camping. If you don't have it, put it on your list now!
I said I was going to re-do my fill spout, but I have not touched it since I hacked it in place right before leaving on a trip. It's working find and looks acceptable, but I may need to re-visit this if/when I do a swing arm for a generator box.
I made an extension out of an old insulated plastic coffee mug. I did sand it so it's pure black plastic.
The water system has been trouble free since I installed it. The nylon tank seems to hold up fine to all the rocks I'm sure I've thrown at it.
