Lots of good advise here. Let me see if I've got it.
I will update to a longer hose so that I won't need to jockey the
Casita around, and keep the old one just in case one of the little nubbins should break off. I'll get one of the all sizes fit all holes, red, adaptors and just in case the red thing won't fit, a rubber donut from Wal-Mart. I won't forget the baby wipes, disposable plastic gloves, and I can use the spray bottle with bleach water on all the soda buttons in Kansas. I can rig a clip for my belt and hang it next to my cellular phone.
Finally at the dump station, I hook the hose to the trailer fitting, rotate the thing on the trailer down, and poke the other end of the hose into the dump pipe. How big is that rock?
Ready to pull the valve and step back. Is it ok to put on my hip boots the first few times? If a carry my fly rod, no one will be the wiser.
I may go out to Bonny Reservoir just north of Burlington, Colorado for a practice run. It's a great little campground with hot showers located close to the dump station just in case I end up ankle deep in "stuff".
