Most service trucks carry hose long enough to pump from the street if the driveway is too tight, so you usually do not need to drag the unit out every week.
On our last addition job the driveway was one car wide with a stone wall on one side. The vacuum truck parked at the curb and ran hose about 60 feet to the standard unit. Drivers will tell you their reach up front if you ask when you book. Call before the first service visit and give them the driveway width and how far the unit sits from the street.
Moving the unit to the curb on service day only comes up when the hose still will not reach or the gravel is so soft the truck will sink. That is a pain and it risks a missed service if nobody is there to roll it. Better to place it where a hose can hit from the street and leave a firm pull-off so the driver is not backing into soft shoulders.
If a truck does get stuck, that is usually on the rental company for the pull-out, but they may push back if the driveway was clearly too soft or blocked and nobody warned them. Flag the tight access when you order and ask what hose length they run. That one call usually settles it.
