Mom should have a discussion with her auto insurance carrier. If they are not driving the vehicles regularly, say a couple times a month, most policies will allow it. But if they are driving it regularly, she needs to make sure she is protected. Father's policy may have a rider for driving other vehicles.
Depends on which UPS trucks you're referring to. For the tractor-trailers, they use a mix of Freightliner, Mack, Volvo, and Sterling trucks. Those come both from vehicles ordered for UPS, and vehicles acquired when they bought out Overnite. The delivery vans have bodies made by Utilimaster, and I believe they're built on chassis from Freightliner Custom Chassis. They also run a number of Freightliner/Dodge/Mercedes-Benz Sprinter vans and Ford F350 box trucks.
