You really have 2 requests: Comfortable for 2 weeks, I have one set of suggestions. But you need to fly with it. So that changes my recommendation. We have a Eureka 4 person tent in a tall configuration that we have flown with. There is a similar tent in production called the Kelty Tallboy 4. It is 5'10" in the center which makes it a little more comfortable. Also, while I know a Scout is Thrifty, considering some of your gear to be disposable might be to your advantage: pick up a ground tarp and a camp chair at a Walmart. Gift it to someone who is driving or donate it to a Goodwill on your way back to the airport.
I know you’re partial to Coleman, but the kelty tall boy is a simple dome tent with a 6’ center. It doesn’t have a covered exterior area if that’s important to you, but the quality is significantly better than my old Coleman.
You're safe! I have similar tents... My fave is my first Kelty dome tent. I won't tell you how old it is, but it's small, waterproof, and a breeze to set up. I also have a Kelty 6 wireless, a Gazelle 3t, a coleman that I've never even set up, a 2 person random cheap tent that I have used twice, and another little dome tent that I have no idea where it came from. And, I'm still looking. I have issues.
How tall is the air mattress? What time of year do you want to go and how many people will help with set up? I’m in middle TN and really only fall and spring are where storms are less unpredictable. Sounds like you are perfect for a larger tent from Walmart like a Coleman. An REI/kelty dome tent is also a good option if your air mattress is not very tall. Get something cheaper to figure out what you do and don’t like/need.
A dome tent should work just fine at that height. They are easy to set up solo and don’t break the bank. I would advise looking into the Coleman tents since they are cheaper and normally a bit bigger but I have spent many nights in a kelty dome tent. Look into the exact set up for the rain fly on staking it out, that will help if there is a storm forecasted. When going on tent size know that if it says 3 people that means 2 people can be comfortable and 3 people need to be super close so always go down 1 person vs what the tent actually says.
it fits my kelty 6 comfortably with space on the size. it was very tight with my kelty 4
Well if you want advice on a tent I could probably try to help you out! Just took a quick pass through the tent options and I’d recommend the core 4 person instant tent for $150 just because they’re already an established tent making brand with great reviews. I personally own a 4 person kelty tent and the quality is really good imo and they’re easy to setup. Some of the kelty tents have these sleeves that the bottom of the poles go into and it makes solo setup a breeze. My issue with instant tents like the one you mentioned, the gazelle t4, etc. is that they’re heavy and they don’t get very compact. But if you have both storage space and space in your vehicle go for it.
