RV fridge filters should be removed and bypassed during winterization. Leaving the filter in is incorrect - antifreeze damages filters and water inside can freeze. Request they replace it.
Travel with winterized RV but expect no water systems. Use campground facilities or de-winterize once reaching warm destination. Plan to de-winterize in Keys and re-winterize for return trip north.
Your RV sewer hose will likely freeze at 25°F, especially with the uphill section that creates standing water. The two-inch rise at your hookup point is particularly vulnerable to freezing.
Low water pressure with 40 PSI at regulator indicates restriction downstream. Check inline water filter, city water check valve, and any winterization valves. Pump running on city water confirms restriction.
