Have the same tent. Our stakes stay at home for Powell trips. We have a 5’-7’ piece of paracord looped on each corner, then we wrap that around a decent sized rock we find/bring over to the tent. Once you have the corners down you can set it up properly. Sometimes after setting it up you can then sometimes add a rock to the middle on each door ends. Never had an issue.
The rocks don’t need to be that big either, like the size of a three ringed binder or green sprinkler cover (sorry all I could think of to compare) work great, one other thing you can do is tie the first rock that size then just stack an additional one on that. Works great, key to that tent is to get the corners tied down first. Then it’s super simple.
Such a great tent, best part of the tent in my opinion is it’s bag. You don’t have to roll it up perfect to have the bag fit over it at the end. Such a good idea. Hope this helps
