We do have an autofill as part of our 3-way water fill switch. We never use it due to the fact that I'm the nervous type. We have 100 gal fresh water tank that handles my wife and I easily for 2 or 3 days, and generally I fill the tank in the morning time if needed and always turn the water off at the hydrant. We use the coach water pump for the shower, and etc. and it has plenty of pressure. When we leave the coach, we always turn the water pump off..... never have had a problem and don't want one. We always hook a pressure valve to the park's hydrant. The pressure valve generally only handles water pressure up to 40 pounds. We have seen some parks water system pressure rise to 60 to 70 pounds at night and this scares me. Most of the time the park will tell you to put a pressure valve at the hydrant as a precaution.
If you hook a pressure valve at the hydrant and it reads 40 pounds and you still have very low pressure in your coach, then the problem has to be in your coach.
Hope this helps and good luck!
