Any tips on sending a door from California to Michigan?

i shipped a door back east last month and used Uship. it was kind of a pain in the *** but was cheaper than UPS ground/freight even with my discount.

i wound up building a pallet/skid with a 1/4" ply box and packed the crap out of it. tracking left a little to be desired, but it arrived within the window and undamaged.
