Hey lumpy, I think we got off on the wrong foot. I'd like to start over.
As for the lowered stance... these vans have a fair amount of ground clearance and even lowering 4-5" still maintain more ground clearance than the average stock height car. The areas of concern are the front bumper valance but with the wheel location so far to the front there is very little hanging off the front so that is not much of an issue. So speed bumps are not a problem unless they are huge which present problems to all cars. Just approach and exit angles are affected and need to be handled as necessary. But easily done for anyone that has ever drove a lowered vehicle. This is assuming you have a modestly static lowered van. Any lower than that would become difficult and they are usually done with a adjustable suspension such as airbags or hydraulics in order to maintain driveability.
The other issue with lowering is wheel and tire dimensions. With the wheel gap closed rubbing can become an issue while driving or turning. Same as lifted vehicles and larger tires. When those dimensions change they will rub. The difference with us is that we cannot simply cut fenders and bumpers for clearance strictly due to cosmetics. So we must find the "best" fitting wheel tire combo for the look we want to achieve and use alternative methods to increase clearances under the fenders such as trimming fender liners and or rolling fender lips to create the space we need to articulate and turn with little to no rubbing.
There are obviously 2 sides to the fence and both have obstacles to cross to make them functional and comfortable but done correctly both can be reliable, comfortable, good looking outcomes. Mine drives great. I am very happy with how it performs and looks and with the airbags in the rear it can haul a trailer and or 8 people with zero effect on ride quality.
I hope this answers your question a little better.
