has anyone made any tractor resembling a "shelter logic" thingy?

hubby and i constructed to what looks like as of right now a shelter logic type thing for our meat chickens( and later re adapted possibly for short time grow out type housing in warmer months..)

it is 10x10 and It is in the driveway right now, i still need to fasted down the tarp all the way and put more piping in for the doorway and maybe adding another crossmember down the length of it in the middle. im making one and once i get that down, ill know how to make another one( i started with 100 meaties 10 days ago so ill need anotehr one in a few weeks)


I would like advice from anyone who has done something similar. we HAVE glued the pieces of conduit together but i would like less sway( from what ive seen just tugging on it) when its going to be drug over the lawn.


Thanks!

ps.. this is what i mean by a shelter logic thingy lol

it mimics the shape(this sells for $500) so far mine costs about $60 witht he best quality tarp i could find
