3/4 ton truck questions

For ED505, in the east from DC up through Maine we have a bunch of strange rules. Some neighborhood's streets are restricted to 10k pound registration or less (ever wonder why Ford builds an F350 with a 10k door sticker?). Some states if over 10k, you are commercial, even if it never works for pay. The left lanes on interstates (with 3 or more lanes) are restricted to 10k or less, and only non-commercial, less than 10k vehicles can use parkways (these have nothing to do with parks by the way). So the OP is from out on Long Island and if he uses the truck for anything but towing the 250/2500 trucks have their place. I don't make the rules, but I have to play by them when visiting the DW's home stomping grounds.
