Water loss is the killer, both while transporting and after planting.
Remove some big leaves from it, put it in a plastic bag or something with a sprinkle of water while transporting and water DEEP every day for several days after planting.
What I do is make deep watering jugs, my area is hot and dry and these have saved many plants. Get a gallon jug, cut a big filling hole in the top while leaving the handle intact, on a corner [I do the handle-corner for consistency] almost on the bottom surface drill a 1/16" or 3/64" hole, debur it if possible, then you just fill the jug and it'll sort of pee out the water in half an hour, this lets the water soak in real deep and wet the whole planted root. This is how you can feed a single plant a gallon of water while only making a 3" wide wet spot.
