Water pressure regulators are a necessary accessory in campgrounds to protect against high and damaging pressures. While most CGs don't exceed 65psi, which is OK for modern campers, some can exceed 100psi which can blow a hose or fitting. That can be a real mess even in an aluminum camper.

The common Camco Valterra brass inline regulators, even the "high flow" models, do a good job of limiting pressure, but they also limit the flow rate. This is noticeable in the shower and when filling pots. If you get an initial high flow and then it noticeably drop off it's the regulator restricting flow. The standard option is an expensive household regulator such as a Watts, but there is now an alternative. It's a Fairview model WR-RV55:

They are available from:

I measured the time to fill a 6 gallon jug from my garden pump at 40psi through 20' of 3/4" hose:

Open hose, no restriction:      29 sec, 12.4GPM
Fairview regulator:                36 sec, 10GPM
Camco Valterra "high flow":    50 sec, 7.2GPM

This should make a noticeable improvement in show flow, especially at low pressure CGs.

I only measured the Camco Valterra high flow unit. It measured 7.2GPM. They have a "normal" unit, which I also have, but I didn't measure it. It is less than 7.2GPM.
