Just back from round trip NM to OH last week, about 3100 miles. Second trip this year and two more to go; although last one will be one-way NM to OH. That's with the motorhome. Made additional trip with my F-650 pickup pulling 26 ft enclosed trailer. F-650 trip was 32K total weight, had all my tools and many car parts, truck bed and trailer both stuffed full.
Reason is retiring and moving to Cincinnati OH. So been making trips out there to haul stuff. Have car trailer behind the MH each trip, with one of my old cars on it. Wife has been driving a vehicle also. Return trip put my small utility trailer on car trailer and have that behind the MH.
Racking up the miles on I-40 for sure! Been taking I-40 from NM to Nashville, then up I-65 to Louisville and I-71 to Cincinnati. Might be a little shorter taking I-44 out of OKC, but that is toll road and it costs too much, plus staying south was warmer route until recently.
