+1 for Stewart...
...Recently a move from Mass to GA took 3 months or more to get the move scheduled.
They do an excellent job, but they are very busy.
The MA to GA was my aircraft. I highly recommend Stewart. My driver was Kelly and he was experienced and very conscientious. He's also a great communicator.
To follow up on a few points made in this thread; yes, Stewart is extremely busy. My wait wasn't quite three months. I was ready to ship on April 21st and ultimately shipped on July 2nd. To be fair, Stewart did offer a pick up date of June 4th but I fly for a living and I was on a trip that week.
Stewart was very busy returning kits to Van's in Oregon because of the quick build primer corrosion issues. But my understanding is the bulk of those returns have been completed. Obviously, returning kits to Van's is not something they normally need to fit into their schedule.
Stewart is not inexpensive but $14K is simply ridiculous. To ship my nearly completed, disassembled RV-10 from MA to GA was about 25% of $14K.
Stewart is equipped for this type of shipping. They have two main clients; Factory Five kit cars and Van's. Their bread and butter is delivering kits from these two companies. Outside of those two primary clients, they have experience shipping disassembled GA aircraft. The trailers are equipped with a crane and (most of) the drivers have experience handling this type of load.
I'm not sure how wide the other RV models are but my RV-10 had just more than one inch to spare on either side after removing the wheel pant axle extensions. I don't know if a typical rental truck is as wide as these trailers and I have no idea how one would go about loading a completed fuselage, with the engine hung, into a rental truck without this type of crane system.
