To avoid the possible leaking into the van syndrome, it is easy to
fill the tank from inside by removing the 3-4" diameter tank cap &
placing the hose in the tank directly at any volume till it's full &
then turning off the hose before it overflows?  It takes more time to
access the tank, but the filling is much faster, you can see how much
water you are putting in, the condition of the tank, pump, hoses etc.
& you get to bond w/ your storage tank & related equipment while
sitting inside?

YMMV,
