Dishwasher install issues on 2016 Fleetwood Excursion

Very simple except for what to do for counter.
I/2 shark bite tee,1/2 shark bite x 3/8 compression straight stop,dishwasher tailpiece,brass dishwasher 90*(3/8 male ipsx3/8x3/8 compression)some soft copper 3/8 tube. Start at sink cabinet and drill 1-1/2 hole in bottom corner and next one until you reach old stove location. Run your copper and hose change tailpiece cut in tee
with valve. Loop the drain line from the hole you drilled in the sink base cabinet and loop it up to the under side of cabinet down to dishwasher tailpiece connection and use hose clamp to secure. If possible zip tie up the hose that you looped up to the under side of counter.
