The 400-N Tariff is the regulations that govern all movers by federal law. They will weigh the truck before and after, but it is still good to know that the estimator's are close...you don't want any big surprises. In the end go with who you like if all things are the same. This is the person you will call if things should go bad. Are you packing yourself? If so, will they give you free used boxes...that can be a bonus too!Oh, another thing, will the move be handled by their agency or are they bringing in a a driver from somewhere else(self haul or line driver is the term)...just a question to ask.
