If you hire a company that uses a big rig to transport multiple customers at the same time, make sure your new home has a driveway that can accommodate the size of the truck. If the truck gets there and they feel they can’t get up the driveway to your house, they will charge you for a shuttle truck. The contract should say what size truck your property should be able to accommodate.
My parents really got dinged on that when they last moved. It cost them nearly $500 extra. The movers were afraid of getting their van stuck on the nearby RR tracks.
