I have given up on the local Uhaul dealers. they are tied to their
stupid computer program that tells them what can be done (no room for
common sense). I finally said Scr%$ you and purchased a new angle iron
5x10 tilt bed trailer. it's fits the 600's with room left over on the
end , and it's the most borrowed piece of equipment I own! that's my
story and I'm sticking with it...your mileage may vary
