I just got back from the Zenith Factory with my 701 Complete Kit (including folding wing option).  The folks there did a great job of loading the UNCRATED kit into a long wheel-base cargo van.  It all fit just fine.  Kudos to the staff ... They wouldn't let me do anything but watch.  Done in less than 40 min.

If you plan to go this route you will need a dozen or so furniture pads for the load.  U-Haul and Ryder do not rent them anymore.  They SELL them at $8-10 each!  Via Craig's List, I found a guy in the Dallas-Ft. Worth area that was getting out of the moving business.  He sold me a dozen (used) for $2 each.  I now have very little use for them (and the 120' of 36" corrugated cardboard in 13' rolls).  I will be happy to give them to any builder who is going to make the trek to Mexico to pickup his/her kit. 

You pay shipping (from the Dallas Area) and I ask that you make the same post/offer to other builders when you finish your pickup.
