We have the Rino and a ten foot extension that I've used once. Stayed at one camp ground that I needed more that 25' of water hose. On board water filter, but if not I would use the in line ones that attach to the hose.
A green outdoor carpet (10x15) that I bought / had cut at Home Depot when I bought the T.T. Easily transported even if wet in the truck bed.
You will probably always be within driving range of a Wal-mart / Dollar store, etc, so don't worry about it.
Most importantly ....ice cold beer and comfortable outside chairs.....lol
