I learned a bit of patience. Sure the dump station takes a while as does fueling up. It is why I go to the truck side when the RV side has lines. If there us only a couple people ahead it us good if there are 10 I pop the park brake and get a dr pepper. My turn comes I will put on my gloves open the hatch and connect. I use the grey tank to flush out the black so it us faster but it is still a max of 180 gallons. The drain time is a few mins. Just take your time and finish off your trip. It us part of the experience. When I adopted this attitude this stuff stopped bothering me. Oh and I drive a diesel truck too and do hate it when the little gas rice burner blocks the only pump.
