Hi from South Dakota and WELCOME to iRV2.
Say.......it'll be VERY helpful and likely generate more help for you if ya kinda describe how you've got your water connection set up. For example, describe what ya have in line right from where you thread the water hose to the campground water bib (or faucet) to where you connect the other end into your rig. Size of hose might be important. Do you use one of those in line water pressure regulators (often brass) in line and if so describe this regulator. What, if any, water filter or filters do you have in line, etc. etc. As Sarah W pointed out, alot of this is often discussed under various topics and reading those can be helpful, but, describing your own specific set up is often more useful for guys like me who don't know a darn thing. It's all part of learning your rig.
