What would be the problem to fill your freshwater at your campsite BEFORE you get to the dump station? Seems like a no brainer to me. My biggest complaint is the design of the “service center” (aka:dump valves and hose hookup area), I swear the “engineers” that designed that area have never owned an RV. There is NO reason the valve handles can’t be accessible while standing next to the rig and that the hose connection can’t come straight out of the compartment without requiring you to get on your hands and knees and practically crawl under your RV to connect. Come on RV designers, listen up, we’re not all youngsters, make it easy for us!!!
