All in All

     So it turned out we ( I ) stressed out over things like the B4 forms that weren't important after all thanks to being military.  We didn't do any forms for my husband's car or our suburban and they came across the border just fine as well.  Over all an easy experience.
     You would do well to pack as much legal food and household goods as possible to bring with you.  We packed a few dry goods and brought butter but I wish I had packed a LOT more in the extra trailer space.  Prices are double to triple on almost all necessities so keep that in mind.  Rolls of toilet paper amongst other things make good packing material and can be re-used.
