   Most wheel jacks aren't rated for this much weight either.   
      
   Landing gear... one of the plans for the connecting tube assembly is   
   snap pins rather than bolts or welding.  Makes it dead easy to make sure   
   both jacks contact the ground at the same time, or close enough.   
      
   While I didn't mention it in the original post I also plan to be able to   
   stand on the drop foot, and then lift the front of the trailer higher   
   than is normal when unhitched to facilitate some types of loading.   
   There is already a tilt down support with drop foot in the rear to   
   prevent back tipping when loading unhitched, or when hitched to a   
   lighter truck.   
      
   I thought about chopping the tail and adding arched ramps, but it starts   
   getting overly complicated.  This is simpler from a fabrication   
   standpoint, and I can keep using the straight ramps that slide into   
   carriers on the bottom of the trailer.   
      
   I will need to pick my final weld-on height with the trailer hitched to   
   the truck to make sure I have enough ground clearance when running in   
   order to maximize everything else.  I'd like to have about 12 inches   
   clearance under the landing pads with the trailer level on the truck   
   with a load.  I'll probably just set them at 13 inches unloaded.
