RV drinking Water Hose

I have used BOTH 5/8 and now 1/2" there is no difference with the amount of water or pressure coming out of my shower or anything else. The lines in these RV's are so small it does not make any difference. Hose size to a house, YES.

More flow...not pressure. Gee whiz.

If you connect to city water then the 5/8's is my choice. I like a good hard shower and if you restrict the size you restrict the flow. Your pressure gauge should not be higher than 45 pounds so go with the larger hose. If you have a hard time coiling a hose I really feel for you if it is freezing and you have to coil your power cord. lol.
By the by there is only one way to coil the hose do not fight it. As for a cord, any cord, if you give it a half twist when coiling it will be a lot easier. I have coiled thousands of cords in construction for 40 years.

I highly suggest logging into "rvfilterstore.com" their hoses and end connections are top quality. Don't waste your time looking unless you are willing to part with your $$$. I purchased three different lengths. Been full timing with them for over two years, still are in perfect condition.

The usual problem with water supply is too much pressure. Use a flow limiter on your water hose connected to a house supply. The diameter of the hose is of little consequence since the water has to go through your pipes in the trailer.

In MOST cases I would agree. With the plumbing lines so small in RV's it really does not matter.

They have high quality Watts water regulators.

As mentioned, your rig has 1/2" plumbing so except for faster filling the FW tank via an open/gravity fill port if so equipped. A threaded connected/piped port would be no difference (i.e. back to 1/2").

Pressure would be based on any restrictions in your rig and what psi the CG provides at their spigot.

Hose quality is a separate discussion.

A larger hose would allow two faucets to be turned on at the same time without as much volume/pressure loss as a smaller hose. Someone taking a shower and someone else flushing a toilet is a good example.

And wouldn't the 1/2" provide more pressure? If that's an issue, which probably isn't considering the recommendation to use a pressure regulator.

Nope.

If water is NOT flowing at all, the pressure would be the same. If some water is flowing, but less than max the hose can deliver, the pressure would be higher in the 5/8 hose.

For what it's worth, the larger hose will work better for longer runs. If you ran 100 feet of hose to your RV, you'd notice a difference in how the fixtures behaved inside the RV. But if your hose is only 10 feet long, you'd be hard pressed to find a difference.
