Circuit 3P

I use a kelty 3 man for car camping- it’s light and plenty of room for gear and myself and enough room for the get times my wife came camping. and I like it enough that I got the 2p backpack version. It also probably way und your budget number

I have a 3 person kelty that has served me well

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.

I own Kelty, North Face and Marmot backpacking tents, and can attest to their durability, ease of use and agreeable weight. I've used them both in the backcountry as well as when going car camping.

I've had great luck with Kelty backpacking tents. You can usually find sales for less than $100 for the 2-3 person ones. They're pretty light and was fine when I got stuck in a storm while motocamping. If you are car camping for now you can skip the cooler and just bring canned/dehydrated food and a pot. Then when you have the funds for some lighter backpacking gear you already have a tent
