Mr. Jing helped fill the RV's water tank to the brim; just connecting a hose would do. The water tank inside the RV was a super-large one; after all, it had to satisfy a family's needs for washing up, bathing, drinking, and the floor heating system too—anything less wouldn't be enough.
As it happened, Jing Shu also wanted to test how the RV's floor heating performed after the modification. The constant temperature water pipes at 40° could ensure a moderately warm temperature inside the RV, plus there was 24-hour availability of hot water for showers; such a comfortable environment was exactly what Jing Shu had always dreamt of.
They fully charged the battery for the German MAN and installed the extra bacterial solar panels Jing Shu had bought on the roof, mainly to test the RV's endurance. Their own BYD Song, once fully charged, could run 180 kilometers.
