Water Pressure
You hook your water hose to the pedestal and lay the hose in the sun. As the sun heats up the hose and the water inside doesn't the pressure inside increase also ? So at the pedestal you have say 10...

If your regulator is at the pedestal, the increase in pressure in the hose due to temp is not going to be enough to cause an issue, since you're starting off at only about 40psi. If your regulator is instead at your RV, any pressure increases in the hose would be buffered by the rest of the municipal system, so again, no issue. What COULD cause an issue is the fact that the hose material will soften with the heat, and given enough pressure, could then fail. Which suggests that the best location for the regulator is at the pedestal rather than the RV.
