How do manage to put a montana 6 up yourself?
OK a brief description, hopefully enough to get the idea.
Idea is to raise it from the rear, one section at a time - to about 60deg to start with. Then stretch the tent, adjust and peg out fully.
Layout the tent and make sure the doors and windows are open to allow air to get in more easily. Slacken off the straps where the poles attach at the bottom. Untie the ropes.
Peg out only the rear corners of the tent
Build up the poles and feed them through the sleeves. Insert the pins into the bottom of the rear poles - you can do the others but need the rear one to start with the others you can do when it's up.
Make sure the poles are all facing with the legs facing the front of the tent and are stretched out so there will be less weight on the rear part of the tent.
With a tent peg in hand, and rope untied, slowly pull up on the rear poles until you get it to about 45 to 60 degrees. That is not fully up. Do it slowly using your weight to allow the air to fill the tent. Peg it out at angle to hold the pole up. Nip around the other side and peg out the other pole.
If you haven't already insert pole pins then, repeat for rear middle pole, should be easier as there is less weight and more air in the tent.
Then middle front - but use this to pull the rear two sections more vertical.
Before you do the front poles peg out the rear ropes at the back windows so you don't pull the whole thing over.
When you get to the front poles you should be able to pull it vertical.
You can then easily pull it properly adjust pole straps peg out etc
Next time I do it I'll take some photos.
