I have used a ATV to haul countless large ladder stands mostly put together and then even used ATV to hand the stand using pulley's
I also find it a LOT easier to carry in a ladder with me to check tree's out FIRST, before making all the effort to place a stand, as be surprised how many times what I THOUGHT was a good location/tree, ended up not being so good from the heights of ladder stands or loc on's, and I also found having a ladder makes life a LOT easier to hang stands period!
I would use a bar or wood to make a place to place ladder ion each front and rear rack, and then pl;ace ladder down using ratchet straps and then can place ladder stands on top, like driving a BIG RIG at times thru the woods, but I have found I can get things on PRIVATE LANDS I have access to, or own, doing this most times!, or sure beats carrying ALL the way!
plus I can also carry a lot of tools on atv as well, like pole saws, cordless tools and ??
this is what I have been doing for 20+ yrs shown with a small ladder and a smaller older 15 ft ladder stand I found on private land I took down, but have carried much larger stands and up to 4-5 at a time doing this
