Place the potatoes in a large pot and cover with cold water by 1 inch. Season the water with salt and bring to a boil. Reduce to a simmer and cook for 10-12 minutes, or until the potatoes are fork tender.
Drain the potatoes and spread them on a baking sheet or large platter. Let cool for about 15 minutes until warm but not hot. Drizzle the pickle juice over the potatoes and let them rest until cooled.
In a large bowl, whisk together the mayonnaise, Dijon mustard, and garlic powder.
Add the potatoes to the dressing and gently toss to coat.
Fold in the dill pickle chunks, red onions, radishes, jalapeños, and fresh dill. Then finally, fold in the chopped eggs. Taste and season with salt and pepper to your liking.
Cover and refrigerate for at least 1 hour before serving.
Just before serving, top with the crushed dill pickle potato chips and additional fresh dill if desired.
